Description : Why do you suppose Martin O'Malley was booed for saying "All lives matter"?
Last Answer : answer:I am only guessing based on what you wrote, since I've not heard of this event, but since this is a Social question My thought is that they may have responded from feeling that O'Malley was detracting, ... dunno. I'm imagining a tiger eating you alive, and I can't say I'd be too concerned.
