No idea there were children in the house? Well ok then, since they put it that way. All is forgiven! After all, nothing is more important than officer safety. Cue "followed procedure; they did as they were trained" excuses. As Mark Steyn has recently put it, "by the book" is no excuse because "the book" is the entire problem. "The book" needs to be tossed out.
Didn't know there were children in the house? Well maybe that should be an assumption before you throw explosives inside peoples homes, just maybe? I'm sick and damn tired of these roid heads acting like every city in America is their own personal Fallujah.
