Actors and actresses can cry and be emotional on cue.
So can politicians, as when Bill Clinton began crying IMMEDIATELY after spotting a camera after the Ron Brown memorial.
Obama shows nothing but phony pretend compassion and empathy. It's not real at all. If it were, he would've had the same compassion and empathy for those killed at Ft. Hood, or Brian Terry, or the Benghazi victims. It's all political posturing.
