MALVEAUX: It's the official goodbye for Defense Secretary Leon Panetta. The Pentagon sends the boss off with a formal ceremony. That's happening today, even though he is likely to be on the job for at least another couple of weeks. Panetta spoke yesterday before Congress, said there will always a debate over how much military power to put around the world.</s>LEON PANETTA, DEFENSE SECRETARY: The United States military, as I've said, is not and frankly should not be a 911 service capable of arriving on the scene within minutes to every possible contingency around the world. The U.S. military has neither the resources nor the responsibility to have a firehouse next to every U.S. facility in the world.</s>MALVEAUX: Former Senator Chuck Hagel, he's been nominated to replace Panetta. That confirmation vote continues and has been postponed. And a look at this massive crowd that filled the streets in Tunis, Tunisia. This was a public funeral of an opposition leader who was shot dead outside his home Wednesday. Thousands of grieving and angry folks marching with his coffin to a cemetery in Tunis. Many believe it was a political assassination. Riot police have violently put down several public demonstrations since that shooting. And, of course, getting back to California, one of our main stories here, the hunt for the former cop now a murder suspect, Christopher Dorner accused of killing three people around L.A. and declaring war on the entire LAPD in a rampage seeking revenge for being fired. Casey Wian is with us from Los Angeles. Paul Vercammen is about a hundred miles away in Big Bear, California. That is where we found, the cops found, Dorner's torched pickup truck. And, Paul, so, I want to start off with you because we heard from the sheriff there and they continue this search even though the weather is pretty bad in Big Bear. They lost his tracks because the ground is frozen, so how are they pursuing this?</s>PAUL VERCAMMEN, CNN SENIOR PRODUCER: Well, they're continuing their search in this area. A number of law enforcement officers are also going in and around on snow cats.
