around wikileaks and founder julian assange. police arrested him on a warrant from sweden. swedish police want to ke him about rape and sexual molestation allegations by two separate women. assange was in a courtroom today and was denied bail for another week. so far there is no sign today's developments have triggered that encrypted file that assange has threatened to release if he was arrested or if he was harmed or if wikileaks was shut down. so exactly how would that actually work? we looked into it. this is from my colleague brian todd. >> reporter: some call it a doomsday file, others a poison pill, he calls it an insurance file to be opened in the event he is captured, killed or wikileaks is taken down. with me is ira writtinkler.
