Dozens of air tankers and National Guard helicopters areng giving support to 3,000te firefighters below. On the ground, theyre lighting backfires to burn out dry brush ahead of approaching flames that threaten thousands of homes. But huge columns of smoke as high as 35,000 feet are making this fire fight especially challenging, says battaliong, chief jeff ohs. Once the energy reaches that level, the column collapses. Thats a big, big problem because then we dont have onee direction the fire is going. Ra its going in several directions. Reporter we saw firsthand how quickly the fire can change when fastmoving flames blocked our exit road and we had to wait it out for two hours with firefighters. At this point, were in a safe zone. Theres no vegetation to burn around us. The best place for us to be is inside the car, but you can see the flames just about 100 yards away from us. But residents who evacuated didnt have that luxury. When i left, we didnt take anything except for a toothbrush and our animals. Reporter so this was your home .

Wilbourn, a convicted bank robber on parol shot 33yearold sean bolton multiple times. As officer bolton lay on the ground, a neighborhood resident grabbed the Officers Police radio to call for help. Please, please hurry up hes shot sirens blaring reporter bolton pulled over when he spotted a 2002 Mercedes Benz illegally parked in a south memphis neighborhood. Officials say the officer had unknowingly interrupted a drug deal. Detectives say wilbourn was the passenger in the vehicle and got out of the car, briefly struggled with bolton, pulled a weapon, then shot the officer. Memphis Police Director toney armstrong.

Reporter boltons death is part of a spike in Police Officer murders nationwide. According to f. B. I. Statistics 27 officers were murdered in 2013.

Moving to politics now, today, the white house said Vice President joe biden would make a good president. Biden is thinking about making his third run for the top job. B. While not endorsing him, a spokesman for president obama said biden has a unique set of skills and experience. John dickerson is our political director and the anchor of face the nation. John, whats behind all this biden talk were hearing, all of a sudden . Reporter well, for months, his friends and supporters have told him he should think about running. Hes taken no formal steps to doing so. His aides have said he would make the final call by august. Adding an emotional component to this was the death of his son, beau biden, in may. On the one hand, that blotted out thinking of anything else. But also, according to columnist maureen dowd, beau biden asked his father to run for president. That report over the weekend is what has gotten a lot more people talking about this. The other thing, of course, ising, that Hillary Clinton has shown some weakness in the polls which some people think creates an opening for biden. Hes not ruling it out, but those ive talked to who are close to him say hes not naivet about how hard it would be to run. Pelley what are some of the obstacles he would face . Well, money and organization. If hes going to run againstn, Hillary Clinton, she has a lot of both. Hed have to catch up quickly, and theres not a drivingion passion for a biden candidacy, which would help in raising money and building organization. Hillary clinton is still very popular among democrats. Joe biden is not ideologically different. Hes not from a new generation. He is of a different gender, but most democrats think that Hillary Clintons gender would help her in a general election. So thats the difficulty. The final point would be, scott, that joe biden has done this before. He knows that it would be a long, hard slog if he ran. Pelley john dickerson, well see you sunday on face the nation. Thanks. For the first time, the federal government will restrict Greenhouse Gases from power plants.

Our Homeland Security correspondent jeff pegues has obtained a u. S. Intelligence bulletin that warns Law Enforcement of a surge in small, lightweight drones flying near sensitive sites. The number and the locations are surprising. Reporter the report warns that the number of drones flying near or over potential targets in the United States is on the rise.

The concern is the growing availability of drones in the United States. Law enforcement officials are worried even a small, light weight drone could be used to surveil targets or carry a small payload of weapons. A recent video posted online showed a handgun being fired from a drone. gunfire there have already been several examples overseas. Isis has been using drones for surveillance to support its attacks in iraq. In 2013, a drone hovered over and then landed just feet from chancellor Angela Merkel during a speech in germany. And in april of this year, a small drone carrying a lowlevel Radioactive Material landed on the roof of the office of the japanese prime minister.

The Police Department there isle now being run by a black chief a veteran of the glendale, arizona, p. D. He took over in july, and Michelle Miller talked to him about the challenges. Reporter a lot of people would ask, why would you want this job . Ive always been known as a consensus builder, and one that can work within the boundaries of racial discord. Reporter as the new interim police chief in ferguson, Andre Anderson knows this town is still recovering from riots touched off last year when officer Darren Wilson shot and killed 18yearold michael brown. This is our city gunfire reporter following last years unrest, the department ofor justice launched an investigation into fergusons Law Enforcement practices. They found Police Routinely profiled and discriminated against african americans. Between 2012 and 2014, 93 of all arrests were of black people. There are Police Officers here that, quite frankly, some of them dont understand the dynamics of many people in the minority community. And to some degree, i would say that its not their fault, because we have to train people to understand the community they serve. Reporter the community they serve is twothirds black. A year ago, there were four black officers out of 52. Today, that number is not much different only five black cops out of a force of 50. But anderson says to look beyond the numbers. I always place the greatest emphasis on getting people with exceptional character and getting people with great decisionmaking skills. So obviously race is a factor, but truly we just need good people. Reporter but the biggest priority for anderson telling cops to just get out there and talk to people. If youre not interacting with the public on a regular basis and youre interacting with individuals that are arrested, it kind of formulates an opinion about people in general, so its going to take some time for us to change the culture. In time, we will get there. Reporter and anderson says he will have some of those reforms in place within six months. But as interim police chief, there are no guarantees that the Ferguson City council will appoint him to the permanent post. Scott, he says hed like to stick around for the long haul to see those changes put in place. Pelley Michelle Miller with the interview tonight. Thank you, michelle.

Pelley today, delta joined pelley today, delta joined other airlines in banning the shipment of trophy animals killed in africa. Delta was flooded with petitions after the death of cecil, a beloved lion in zimbabwe. We wondered what big game hunters have to say, and anna werner found out. Were sickened by what weve seen because, unfortunately, it tends to give people the wrong impression. It causes people to have, to some degree, a kneejerk reaction. Reporter North Carolina attorney Kieran Shanahan is talking about the worldwide outrage after a minnesota dentist was named as cecils killer, luring the lion off protected land where hunting is not allowed. Shanahan has hunted in three african countries and killed both an elephant and a lion he says, all legally. But big game hunters themselves have become the targets sincel cecils corpse was discovered. Walter palmer said he paid about 50,000 for a permit. And zimbabwe officials are now investigating a second american, dr. Jan sseski. But shanahan says, done properly, hunting offers benefits. T the money from the permit helps conservation efforts and can bring muchneeded jobs to many african countries. A 2009 report by an International Conservation group says hunters kill about 600 lions a year, and there are only about 25,000 african lions left. Jeff blunken is with the International Fund for animal welfare. Any time an american or foreigner goes to africa to huntme a species known to be in decline, its going to be a question, not just of ethics but is it sustainable and is itng even being done legally . These animals are magnificent. I can tell you the conservation hunters like myself respect and appreciate these animals, and we believe that the manner in which we ethically hunt them is one that im proud of. Reporter neither doctor responded to our request for comment. And, scott, u. S.
