It's horrific to see this happen. I hope that people make it out of this ok, and they get to bottom of who did this. Seeing these kinds of senseless attacks on the innocent is just disgusting.
Agreed. I try to be very understanding of the fact that it is usually the winner that decides who is the "good guy" and the "bad guy" in history, but doing something like this is "bad guy" regardless of the reason. Nothing but a senseless tragedy. My thoughts are with anyone who has friends and family affected.
In addition one explosion could be accidental, two not so.
