NBC's John Larson showed us USNavy maneuvers off the coast of San Diego where submarine hunting exercises have endangered marine mammals for a decade, killing whales with deafening sonar pulses. Warships now practice keeping their distance…the murder of an opposition politician in Nairobi enflamed Kenya's post-election violence. NBC had Martin Geissler of its London-based partner ITN file an update: "I think now it has gone beyond politics. It has become simply tribal ethnic violence, deep-seated resentment at work here. It is now not police beating back protestors but two tribes trying to get at each other. I think the genie is out of the bottle here in Kenya. And it is difficult to imagine what the politicians can do now to push it back in."
