Nobody would be hurt? For godsakes, man, there was gunfire involved and children in the house. It could have easily turned into a bloody massacre. I don't care if they have a warrant or not, you don't go bust someone's door down with guns firing. If they are unsure of the situation they shouldn't have weapons drawn. Is it their fault they got bad information? No, but it is their bloody fault for acting on that bad information. The cops were lucky, that is all. Next time they pull this sort of crap, the next innocent house they shoot up may have deaths involved.
