years ago, long before pbs, i was interviewing a guest one night and i tell the name in the book, robert townsend actor, director, producer. he was on my b.e.t. show. i was in d.c. and he was on a satellite feed in l.a. and long story short, he'd done a movie that halle berry was in. i thought it was a horrible film. i didn't like the movie so one of my camera guys, we're about to go on the air, one of my camera guys goes, did you see the movie? i said, it was horrible. i love robert's work but i hate this movie. long story short, my microphone is open and robert's sitting in l.a. and hears everything i'm saying about how bad i think this movie is. it made for a very contentious conversation when we went live on the air five minutes later. that was the mistake my sound guy made having my mic open but i learned an important lesson, even when you think nobody's listening, somebody's listening. now, stuff we think is private on cell phones and internet, email, all the stuff you think is private can go public pretty quickly. >> isn't it therefore harder to fail up when everybody knows you failed? >>

townsend, national security contributor, thank you. >> thank you. >>> we are learning more about allegations that libyan women have been raped by troops. here is nic robert. >> reporter: in this makeshift rebel jail, this desserter tells us what he saw before he fled his post. i saw cell phone video of several soldiers raping two school girls, 15 and 17 years old during six days in tripoli, he says. as i was told, they were acting on military orders. he tells me he ran away from the army but he realized officers were giving soldiers sexual stimulants and uppers to keep them awake. i found viagra and uppers, he says. before a raid, they would hand them out to keep us awake for 72 hours. we were told, when you go into a house, it's all yours. you can take what you want, rape the women. impossible for us to verify his claims, however, they were echoed by more prisoners in a different jail. they all surrendered on the 24th of april, a month ago. i've been to talk with them already. those that don't want to appear on camera, have moved to one side. the prisoners were going to meet the ones that agreed to talk to us. rape by soldiers was common, this prisoner
