Basketball: Heat scorch Nets 105-85

NEW YORK: LeBron James and the NBA champion Miami Heat ended the Brooklyn Nets' home winning streak in emphatic style Wednesday with a 105-85 triumph at the Barclays Centre.

The Heat shot 51.8 percent from the field and made 11-of-19 from three-point range to notch their 13th straight victory over the Nets -- including a sweep of all three regular-season games on the schedule in this campaign.

Miami bounced back from a double-overtime loss at Boston on Sunday, and halted the Nets' eight-game home winning streak.

Hours after Nets forward Reggie Evans said during his team's morning shoot-around that the Heat's 2012 title was devalued because it came in a lockout-shortened season, the champs showed they remain a cut above.

James scored 24 points with nine rebounds and seven assists. Dwyane Wade added 21 points and Chris Bosh scored 16 for a Miami team that broke open a close game with a 36-14 third quarter.

Brook Lopez, named to the All-Star game in place of injured Rajon Rondo of Boston on Wednesday, scored 21 points and Joe Johnson contributed 16. But the Nets were undone by 19 turnovers, including eight in the key third period.

The Heat continue a four-game road trip on Friday at Indiana and wrap it up on Sunday at Toronto.

Teen who performed at inaugural events shot dead

STORY HIGHLIGHTS

• NEW: Chicago mayor: "We have a responsibility to see a stop to this"


• Hadiya Pendleton, 15, was shot dead in Chicago on Tuesday


• Last week she performed in events surrounding President Obama's inauguration


• "Just a matter of days after the happiest day of her life, she's gone," Sen. Dick Durbin says

Chicago (CNN) -- A teen who performed at events around President Barack Obama's inauguration was shot to death in Chicago this week, and now her story has become part of the debate in Washington over gun violence nationwide.

The shooting death of 15-year-old Hadiya Pendleton came up in a U.S. Senate hearing and a White House press briefing Wednesday.

"She was an honor student and a majorette," said Sen. Dick Durbin, D-Illinois. Performing at inaugural events last week "was the highlight of her young, 15-year-old life," he said.

Speaking at Wednesday's Senate Judiciary Committee hearing on gun violence, Durbin mentioned Pendleton's death as he argued that more must be done to stop gun crimes.

Giffords: 'Too many children dying'

"Yesterday, in a rainstorm after school, she raced to a shelter. A gunman came in and shot her dead," he said. "Just a matter of days after the happiest day of her life, she's gone."

The park shelter where she was shot is just a mile from Obama's home in Chicago.

White House spokesman Jay Carney described her death as a "terrible tragedy."

"The president has more than once, when he talks about gun violence in America, referred not just to the horror of Newtown or Aurora or Virginia Tech or Oak Creek but to shootings on the corner in Chicago or other parts of the country," Carney told reporters. "And this is just another example of the problem we need to deal with."

2013 has gotten off to a deadly start in Chicago -- Pendleton was the year's 42nd murder victim. No arrests have been made in the case, police said Wednesday.

In 2012, 506 people were slain in the city.

Chicago Mayor Rahm Emanuel described Pendleton Wednesday as "what's best in our city, a child going to school who takes a final exam, who had just been to the inaugural."

"We have a responsibility to see a stop to this," he said. "And all of us are responsible."

Pendleton was shot just blocks away from her high school on the south side of Chicago, CNN affiliate WGN reported.

LaPierre, the NRA's heavyweight

Police told CNN affiliates that the teenager had no gang affiliation and likely was not the intended target.

"There has to be an end to it. It's just too much. The children cannot go to school. They're in fear," Bonita O'Bannion, who lives in the area where the shooting occurred, told CNN affiliate WBBM.

Carney said the president and first lady's thoughts and prayers are with Pendleton's family.

"And as the president said, we will never be able to eradicate every act of evil in this country," Carney said, "but if we can save even one child's life, we have an obligation to try when it comes to the scourge of gun violence."

Obama: "No doubt" Congress will pass immigration, gun bills

Obama: "No doubt" gun, immigration bills will pass in coming months

There's more bipartisan support in Congress for comprehensive immigration reform than gun control legislation, President Obama said tonight during an interview with Univision, but qualified that even under his proposal, illegal immigrants shouldn't be harboring expectations that they'll be granted citizenship "manana."

"Even under our proposal, this is not a situation where overnight, suddenly people all find themselves as citizens," Mr. Obama told the Spanish-language television network. "They're going to have to go to the back of the line. We're going to have to clear out the existing line, backlogs we have in terms of illegal immigrants, because they did it the right way. We shouldn't punish them for breaking the law.

"...What we don't want to do is to create some vague prospect in the future that somehow comprehensive immigration reform that includes a pathway to citizenship will happen manana," he continued, chuckling softly at the somewhat awkward injection of the Spanish word for "tomorrow." "But we have to put that in place at the outset, and make sure people are clear that this pathway is real and not just a fantasy for the future."

Asked whether he was in a standoff with Sen. Marco Rubio, R-Fla., the son of Cuban immigrants who has said he will not support a bill that does not put border control ahead of a path to citizenship, Mr. Obama said no, but pointed out that the number of people crossing the border illegally has dropped "about 80 percent since 2000."

On Tuesday, the president delivered a speech in Las Vegas outlining his immigration plan and applauding a bipartisan group of eight senators that has offered up proposals as well. In an interview today with another Spanish language network, Telemundo, he specified that he's hoping immigration reform that includes a pathway to citizenship can be passed in the next six months, but "certainly this year."

Meanwhile, despite facing more resistance from the right on tightening gun laws, he said he has "no doubt" that Congress will be able to put through legislation on gun control, as well as immigration.

Obama: Legalization for illegal immigrants won't happen "ma?ana"

"On the gun issue, you're starting to see gun owners, people who traditionally have opposed gun control, saying, 'You know what, when 20 of our children are shot by somebody who is disturbed, and when it is that easy to get these high-clip magazines that can fire off hundreds of shots in a few minutes, then it's time for us to do better job on background checks, to get control of these magazine clips, to really crack down on gun trafficking," Mr. Obama said in the Univision interview.

The Senate Judiciary Committee today held the first congressional hearing on gun violence since last month's massacre at a Newtown, Conn., elementary school, that left 20 children and six adults dead. Star witnesses included former Rep. Gabrielle Giffords, D-Ariz., who survived a shot to the head two years ago during an assassination attempt that left six people dead, and her husband on one side, and NRA CEO Wayne LaPierre on the other.

Both gun control and immigration "will end up generating some opposition," the president said. "There will be passions on both sides. But I'm generally encouraged that the Senate seems to be having a serious conversation about these issues."

No Device Eliminates Concussion Risk, Experts Say

As the long-term consequences of concussions become clearer, a cottage industry has popped up to sell athletes and worried parents products designed to mitigate risks of concussions that even helmets cannot prevent.

Despite the bold claims of some companies, however, many experts say the Holy Grail in contact sports -- a device that prevents concussions -- simply does not exist. Indeed, experts say, there is no proof that any current device significantly reduces the risk of concussions beyond the protections already provided by helmets.

"Nightline" found several products for sale online that aim to reduce the risk of concussions or even alert parents and coaches when a kid has supposedly taken a concussion-level hit. The claims the manufacturers make are often breathtakingly reassuring.

Concern about the risk of concussion is mounting at every level of the gridiron from the NFL to colleges and even high schools. Concussions are the most common injury among high school football players.

Jennifer Branin, whose son Tyler Branin is one of the stars of the Woodbridge Warriors high school football team in Irvine, Calif., said "it was scary" the first time he had a concussion.

"He had lost his balance on the field," she said. "He got up and tried to continue, but couldn't keep his balance."

She said the effects of the concussion lingered, causing Tyler to miss a week of school and football practice. Even months later, he complained of difficulty concentrating in class.

Parents such as Jennifer Branin, who is president of the team's booster club, and her husband, Andy Branin, a former college football player himself, were looking for a way to support their son's desire to play football while also keeping him safe.

"He wants to play and, as a mom, you may want to put bubble-wrap around them and protect them forever, but that's not going to happen," she said.

So Jennifer Branin decided to do something. She raised money to buy the team helmet inserts by Unequal Technologies for added protection.

Unequal Technologies, one of the highest profile players in this new market, described its product explicitly on the box as "Concussion Reduction Technology," or "CRT." It is a strip of composite material including bullet-proof Kevlar that is designed to stick inside the helmet as a liner to the existing helmet pads.

Unequal Technologies uses its material in products ranging from padded sleeves to shin guards. The company counts NFL players and X-Games athletes among its fans.

On board as paid spokesmen are Philadelphia Eagles quarterback Michael Vick and James Harrison, a linebacker for the Pittsburgh Steelers. Harrison is one of the hardest-hitting guys in the NFL and said he uses Unequal Technology's liners in his helmet.

"I don't know what it's made of but it works," Harrison says in one of Unequal's promotional videos. "I really don't feel like I'm taking a risk."

Vick wasn't wearing the CRT product when he suffered a season-ending concussion in November, but he has since promised that he will be wearing it when he returns to the field next season.

Rob Vito, founder and CEO of the Kennett Square, Pa.-based company, said he worked with scientists to create a military-grade composite material that can help protect athletes from all kinds of injuries from head to toe.

RIM faces make-or-break launch

NEW YORK: It's the moment of truth for BlackBerry maker Research in Motion.

The Canadian company Wednesday will officially launch the BlackBerry 10, an effort that some see as the company's last, best chance to remain a player in a smartphone market it once dominated.

RIM burst on the scene with the BlackBerry in 2003. That was long before the iPhone and other competing technologies emerged to steal control of the market from RIM with their more consumer-friendly smartphones.

The company boomed as the maker of "crackberries", a nickname stemming from the addiction the phones engendered in users.

But now, unless the Blackberry 10 is a hit, RIM faces becoming a footnote in an increasingly competitive market led by Apple and rivals who use Google's Android operating system.

"The importance of this launch cannot be overstated," said Ramon Llamas, an analyst at the research firm IDC, "There's going to be a lot of work that needs to be done to earn back respect."

RIM touts the system as a big change in smartphone technology.

"This is an entirely new operating system," said company spokesman Nick Manning, "We think it's the first entirely new mobile operating system in about five years."

RIM says the system will break new ground by allowing customers to flip between applications seamlessly and without first passing through a home page, to boost efficiency and multitasking.

Another key asset of BlackBerry 10 is what RIM dubbed the "BlackBerry balance", a system that allows users to separate professional communications and applications from music, photographs and other personal items.

Such an option means that if a user changes job, his or her former company can disable the device's corporate side without affecting personal data.

RIM's recent performance on Wall Street suggests the market is open to the BlackBerry 10. Shares have risen more than 30 percent since the start of the year, although they dropped back over the last two sessions.

Gartner analyst Phillip Redman said RIM still has a strong constituency of business users who prefer its hard keyboard and its reputation for strong network security.

While Redman doesn't think the BlackBerry 10 will surpass Apple's iPhone or Android products, the device "has great comeback potential", he wrote in a recent blog entry.

But others see only a modest opening for RIM given the cutthroat competition in the smartphone market.

"We don't buy the hype," Citi analyst Jim Suva said in a research note, pointing out that rivals such as China's Huawei are also entering the market.

Sterne, Agee & Leach analyst Shaw Wu noted that many of the high-end customers to which RIM is marketing have already migrated to other devices.

"We see the company getting a degree of traction in this higher end market, but doubt there is a return to its former glory," Wu said.

Clinton Talks 2016, Stands by Benghazi Testimony

In her final television interview as Secretary of State, Hillary Clinton told ABC's Cynthia McFadden that she is "flattered and honored" at the intense interest in whether she might run for president in 2016.

But Clinton maintained that right now she's "not focused" on a presidential campaign; instead she said she wants to return to a "normal" life when she steps down from office on Friday.

Watch Cynthia McFadden's full interview with Secretary of State Hillary Clinton on "Nightline" tonight at 12:35 a.m. ET

Clinton's first order of business, she said, will be sleep.

"I hope I get to sleep in," she told McFadden with a laugh. "It will be the first time in many years. I have no office to go to, no schedule to keep, no work to do. That will probably last a few days then I will be up and going with my new projects," she said.

"I have been working or attending school full-time since I was 13. This is going to be new for me. I don't know how I'm going to react to it, to be honest."

Clinton has had no trouble articulating her reaction to what has arguably been the darkest chapter of her tenure as Secretary of State: the Sept. 11 attack on the U.S. consulate in Benghazi, Libya, in which four Americans, including Ambassador Chris Stevens, were killed.

Final Farewell: Hillary Clinton Steps Down as Secretary of State Watch Video

Secretary Clinton had a heated exchange with Republican Senator Ron Johnson during her five hours of testimony before Congress about the attack last week. Johnson accused the administration of misleading the American people about the cause of the attack, when UN Ambassador Susan Rice, on Sunday political talk shows, blamed it on protesters.

Clinton snapped back at Johnson, "Four Americans are dead. What difference does it make?" For that, she has been sharply criticized by some conservatives.

Clinton said she "absolutely" stands by her response to Johnson, maintaining that the administration has been transparent with the information it knew, when it was available. Clinton said partisan politics have no place in a response to a terrorist attack against Americans.

"I believe that we should in public life, whether you're in the administration or the Congress, de-politicize crisis and work together to figure out what happened, what we can do to prevent it and then put into place both the institutional changes and the budgetary changes that are necessary, " she said.

"When someone tries to put into a partisan lens, when they focus not on the fact that we have such a terrible event happening with four dead Americans but instead what did somebody say on a Sunday morning talk show? That to me is not in keeping with the seriousness of the issue and the obligation we all have as public servants"

FULL TRANSCRIPT: Sec. of State Hillary Clinton's "Nightline" Interview

Asked about her health, Clinton said her recent illness, concussion and blood clot were all a surprise.

"When I got sick and fainted and hit my head I was so surprised, and I thought I would just get up and go to work. And thankfully I had very good medical care and doctors who said, 'No we'd better do an MRI, we'd better do this, we'd better do that,'" she said, calling herself "lucky."

"I know now how split second beset by a virus and dehydrated, what it can do to you."

Though she confirmed she is wearing special glasses to help with double vision, a lingering issue following her illness, Clinton said that she expects to be fully recovered and operating at "full speed" soon.

The Secretary told McFadden that if she does decide to run, she would have "no problem" making her health records public.

"Of course, that goes with the territory," she said.
