Even the guys who went in get shat upon here.
You keep bringing this up, which I understand, but it rings a bit hollow. Sorry to be blunt, but 19 children are dead. ANY adult who could have stopped any of them from dying deserves to be shat upon.
And I'll say it again, from my perspective: good on the guys who went in, but it was too late for an indeterminate number of citizens who died. Who, in this case, also happened to be wounded children doing what they'd been told by their adults: call 911 and The Police will come for you.
Except in this case, they didn't come soon enough. Speaking for myself, NOBODY in that hallway gets a pass on that.
