The first woman u. S. Attorney for the Southern District of new york, white led prosecution teams that convicted mob boss john gotti, a vicious mob killer who had escaped prosecution by tampering with juries. White kept her jury anonymous and sequestered. She built the best set of terrorism prosecutors in america, convicting the blind sheik for conspiracy to bomb the United Nations and other new york landmarks. She also convicted ramsey youseff for the 1993 World Trade Center bombing. And she was on osama bin ladens trail before anyone, indicting the al qaeda leader for the deaths of 18 u. S. Soldiers in somalia in 1993, charges that later included the 1998 bombings embassies in kenya and tanzania. So id say thats a pretty good run. You dont want to mess with mary jo. Mary jo does not intimidate easily. And thats important. Because she has a big job ahead of her. The s. E. C. Played a Critical Role in protecting our Financial System during the worst of the financial crisis, but theres much more work to be done to complete the task of reforming wall street and making sure that american investors are better informed and better protected going forward. Reporter for the last ten years, white has been in private practice defending some of the worlds biggest banks against s. E. C. Charges. Now, historically, these big banks have delayed or evaded s. E. C regulations through better lawyers. In white, these big banks may meet their match. Pelley major, thank you. Well, a lot of wall streets big names are in davos, switzerland, for the World Economic forum this week, and thats where we find anthony mason. Anthony, what are they saying about the nomination of Mary Jo White . Reporter well, scott, the thing you have to remember here is the s. E. C. Was a laughing stock when it missed the Bernie Madoff ponzi scheme, and it spent the last three years trying to restore its reputation. Under the outgoing enforcement director, robert guzani, himself a former prosecutor, it has had a Record Number of cases including 180 Insider Trading cases. But the appointment of Mary Jo White is a sign the pressure is not going to let up. If anything, theyre going to be turning up the heat at the s. E. C. Pelley well, anthony, while you were in the chilly alps, we got a lot of good Economic News here at home today. We saw that layoffs are down initial claims for Unemployment Benefits hit 330,000, the lowest level in five years. And on wall street today, the s p 500 briefly crossed 1,500 for the First Time Since 2007. It closed just under that. What are you hearing from the worlds bankers there . Reporter well, scott, i spoke with Christine Lagarde the head of the International Monetary fund, today, who, like most here, agrees the atmosphere is much more optimistic than it was a year ago. But lagarde is more guarded than most, and she calls this a make orbreak year for the global economy. You look at the u. S. , the fiscal cliff has been avoided, but there are decisions that have to be made in the course of 2013 concerning fiscal deficits, concerning the debt ceiling, which is why 2013 is a make or break. Reporter if those decisions are postponed again . Well, it will be pushing the can down the road yet again, which was a reproach that we made against the europeans, and i dont think that the u. S. Should fall in that trap. Reporter lagarde says governments and legislators cant be allowed to let up or slip back, that we cant go back to business as usual. Pelley anthony, thank you very much. Democratic senator Dianne Feinstein of california introduced legislation today to reinstate the federal ban on assault weapons, but she acknowledged that supporters face an uphill battle. Nancy cordes is at the top of that hill tonight in washington. Nancy. Reporter scott, the bill that she and other democrats introduced today is even tougher than the assault weapons ban that congress let lapse back in 2004. This bill would ban the sale of 157 different militarystyle firearms. Flanked by Police Officers doctors, and mayors, senator Dianne Feinstein of california made her case today for banning the types of weapons used to carry out mass shootings. They fall into the hands, one way or another, of grievance killers, of gangs, of those who are mentally unstable or ill. Reporter the bill would stop the sale and manufacturing of semiautomatic weapons with military features such as detachable stocks, which make the guns easier to conceal. Magazines and drums that hold more than ten rounds would also be outlawed. Feinstein also asked half a dozen gun victims to share their stories, to give the measure a human face. Lilly habtu was shot three times at virginia tech. I have a bullet still in my head. I was shot in the jaw. Its one inch. Its one millimeter away from my brain stem. Reporter but the ban faces stiff opposition from conservatives, such as Senate Republican leader mitch mcconnell, who released this robocall in his home state of kentucky. President obama and his team are doing everything in their power to restrict your Constitutional Rights to bear and keep arms. Reporter and it will be tough for feinstein to win over some democrats from conservative and rural states. Whats your message to democrats who oppose this . Look, the message to democrats is, see what your silence does . There will be more of these. These arent going to end. Reporter there are more than 2,000 types of hunting and sporting weapons that are not involved or affected by the ban. But, scott, the push for the ban could end up taking a back seat to measures that have more bipartisan support, like a move to strengthen background checks for gun buyers. Pelley well, nancy, in senator feinsteins home state the police in fontana, california, are taking a different approach to fighting gun violence. Theyre arming the officers who protect schools with high powered semiautomatic rifles. And we asked Bill Whitaker to tell us more about that. Its heartbreaking that we have to resort to this level of preparedness. Reporter the Fontana School district chief of police is billy green. His 14 officers protect 42,000 students. Last october, green spent 14,000 to buy each officer a semiautomatic rifle. Fontana is one of the first School Districts to publicly acknowledge having such weapons on campus. By day, theyre locked in patrol cars or Police Lockers in school buildings. So these are militarystyle weapons. Yes, sir. Theyre similar to the platform of what you would see on a. R. 15 or an m16, all made by colt, an american manufacturer. Reporter there has never been a gun death at any Fontana Schools. Chief green says the newtown shooting convinced him hes doing the right thing. To say that nothing like that could ever happen on one of our campuses here is irresponsible. We need to plan for this. We need to be prepared for this. Reporter many parents and teachers didnt know until this week he bought the military style rifles. School board member sophia green says the money would be better spent on counseling a troubled student. But it will be like a blood bath. He has a gun, the police has a gun. All. You know, i dont think thats the way. The avenue we want to take. To the people that have that opinion, my question would be when . Do we wait until theres been a tragic loss of life . Reporter chief green says he can bear the criticism. He couldnt bear the loss of even one students life. Bill whitaker, cbs news, fontana, california. Pelley senator john kerry today appeared before the Senate Foreign relations committee, a committee that he chairs, as it held a hearing on his nomination to be secretary of state. Talking about some of the worlds hot spots, kerry said the u. S. Will do whatever it must to keep iran from developing a nuclear weapon. And about the Syrian Civil War kerry said time is running out for the assad dictatorship there. Outgoing secretary of state Hillary Clinton testified before the same committee yesterday about the new terrorist threat in north africa, in mali. But this is going to be a very serious ongoing threat. We are in for a struggle, but it is a necessary struggle. We cannot permit northern mali to become a safe haven. Pelley fighters linked to al qaeda have taken over parts of mali. The french sent in troops recently to push them out, and the u. S. Air force is helping to carry the french troops there. So we sent Elizabeth Palmer to this new center of terrorism. Reporter malians along the road cheered and waved frances flag as a convoy of hundreds of french soldiers and their weapons drove toward the town of diabaly. To people here, these are the troops who chased Al Qaeda Linked fighters away. Life is now returning to normal. Diabaly was the closest the islamic militants got to the capital bamako. But they only stayed for four days before the french government launched its attack. In diabaly, there was never any ground combat. The french simply hit the islamists from the air and destroyed their equipment and ammunition. That was enough to get them on the run. It was welcome news for the boubakar family. We met them on the road with a cart full of household goods. The extremists had marched sinanta away at gun point and tried to pump him for local knowledge. Are you worried for your family that the islamists will come back . translated oh, yes. Reporter cobbla says shes still having nightmares. Though in the end, the fighters did let him go, the whole family has decided to head up the road where they know there will be troops to protect them. These are the malian troops who, along with the french, are occupying the town that just a week ago was the front line. They say the islamist fighters have retreated but theyre not taking any chances. And the people are grateful. They say the fighters may have disappeared, but the threat will remain until its certain theyre never coming back. Pelley Elizabeth Palmer joins us now in diabaly, mali. Elizabeth, whats next in the French Military campaign . Reporter well, the french are securing this area, but they are still actively fighting up north where there are believed to be much larger concentrations of islamic militants, especially in two big cities. Theres active bombing going up there. We know that. But theres an information blackout no land lines, no cell phones, and no internet. So its very hard to know exactly how fast they are or are not advancing. Pelley elizabeth, thanks very much. As we first reported last night, the pentagon is lifting the ban on women serving in combat. The official announcement came today from defense secretary leon panetta, and general martin dempsey, the chairman of the joint chiefs of staff. Panetta said not everyone can qualify for combat, but everyone is entitled to the chance. What is causing batteries on the 787 dreamliner to burn . Well investigate.

Pelley today, federal pelley today, federal investigators say they still dont know what caused batteries to burn in two boeing 787 dreamliners. And until they figure that out and how to fix the problem, none of the planes will be allowed to fly. We asked Sharyl Attkisson for the latest on the investigation. Reporter more than any other plane, the dreamliner relies on lithium ion batteries to help power its advanced systems. Theyre lighter and more powerful than older battery types. But they contain a highly flammable liquid electrolyte. Federal investigators are examining the disassembled battery from the 787 that caught fire in boston january 7. George bromagain worked for eveready for 40 years, and says lithium ion batteries are bundled together for the 787 and that increases the risk. These fires burn at a very high temperature, so theyre just very dangerous fires. Reporter the boston fire and the burnedout battery on a dreamliner in japan are not the first time lithium ion batteries have caused problems. In 2011, a chevy volt lithium ion battery was damaged in this crash test. Three weeks later, it burst into flames. Chevrolet installed a number of fixes to prevent fires. Safety features were also added to lithium ion batteries in some cell phones and laptops after 56 million were recalled for risk of overheating and exploding. Boeing says lithium ion batteries best met the performance and design objectives of the 787, and based on everything we know at this point, we have not changed our evaluation. Bromagain considers the safety of lithium ion batteries on plane questionable. From what i know about the incident, i would not fly on a dreamliner tomorrow. That. I just wouldnt feel that it was appropriate or safe. Reporter experts we spoke to believe in the promise of lithium ion batteries, scott including for airliners, but they just arent sure its safety has been perfected. Pelley sharyl, thank you. From too much heat to too much cold snow is on the way tonight from the great lakes to the northeast, adding to the deep freeze. On Mount Washington in new hampshire, the wind made it feel like 70below some morning. It was still well below zero in the upper midwest. In minnesota, a waterfall turned into an ice wall. Beautiful.
