to a human rights group today, about 400 people have been arrested since this unrest began in syria five weeks ago. richard engel in benghazi, covering the region, thank you very much. here with me now former congresswoman jane harman, now the president of the bipartisan woodrow wilson center. first of all, in syria, what we re hearing, latest reports that security forces in duma mobilized combat gear, trucks with machine guns, latest eyewitness reports. everything we re getting from there is so fragmented because we don t have people on the ground. al jazeera is there, very few foreign reporters. what about the u.s. response? i was on the phone with the white house officials and they re saying nothing yet. it will be targeted financial sanctions, additional sanctions. but the impact on this regime probably minimal. our leverage is minimal. let me thank you, first, for your on air tribute to sidney
