"And especially post-Columbine, the cops know they can't just wait these killers out..."
Well We have the shooting last week. And the gunman did not start shooting then until they stormed the building. Granted that he was abusing the children, and that is of great concern. But I would rather my children were returned to me abused rather than expired. I am not saying that the gunman in either case would not have shot the children anyways. They very well might have. But we will never know.
The cops had barely arrived when the gunman told them to retreat. And then only a few seconds later he started shooting.
You are completely off-base here and I would hope you stop this.
Columbine happened less than 1/2 mile from me, many kids in my community were involved (mine were too young thank GOD).
The biggest lesson of Columbine that still reverberates in the community is never again will LE sit outside while kids are dying inside. The idea is to be in fast (as I understand they were in Bailey, within minutes they had SWAT and deputies in the building)
I would never second guess LE, they did what they thought best in all instances, but at least in colorado, you can bet that the authorities will be on the inside quickly, no matter what it takes. I think overall this is by far the better plan.
