I have asked this on my twitter account. Especially since there were military in the crowd.
1. This is after a man was left to die in NoVa after he was struck by a bus.
2. A woman from France attempted to walk across the metro rails after getting confused.
I am not ashamed to admit that I would have kissed the ground or ran unless I was well positioned behind him with some kind of weapon.
