to explore this issue, i'm joined by stephen rapp. he's the former u.s.assador at large for war crimes, and is now sits on the board of physicians for human rights. and issie lapowsky, a senior writer covering national affairs and technology for wired magazine. first i want to start off with you both, stephen, you first. what do you think of what happened when youtube pulled down these videos? >> well, i think it's very unfortunate. this is primary evidence of massive violations. physicians for human rights has documented almost 500 attacks on medical facilities, more than 800 doctors and medical personnel killed, in, you know, an enormous number of incidents and an enormous number of facilities. to build the evidence for these cases you really need to see the pattern of all of it. removing it, i think, eliminates what's needed in the future if we're going to have accountability, if we're going to in the future begin again forcing this norm that protects humanitarian workers, protects the health of innocent civilians. >> sreenivasan: issie lapowsky. >> ye
