I too, think they should not have waited so long to go in, but to blame the deaths on the police is ludicrous and shows a complete lack of understanding of the concept of RELEVANCE. 2 kids are at fault, the rest were reacting in the heat of battle.
If those officers had rushed in, instigating a heavy gun battle with collateral injuries(not saying that would have been the result, but it was a significant risk), you would probably be the first and the loudest shouting how "as long as you live, you will never forget the images of those stormtroopers hastily charging the building, killing children, a graphic picture of excessive force and poor judgement."
Do you remember the shootout the LA Cops had with the body-armored bank-robbers?
The cops were outgunned, because 9mm and shotguns weren't stopping the perps, because their BODY ARMOR PROTECTED THEM!
Why do we have SWAT teams dressed like Ninjas, wearing body armor if they are AFRAID OF GETTING THE ARMOR SCRATCHED!
There was NOTHING Klebold or Harris HAD that would have penetrated the armor, but the SWAT Cops COWERED OUTSIDE!
Oh, let's not forget the Cop who is being stonewalled for...he fired off 51 FRICKIN' rounds from a full auto HK-94...that's 1 1/2 CLIPS...ON FULL AUTO!
Now an innocent kid is dead, and you want to join in the LEO Hallelujiah Chorus?
Same request to you as I made to Dane (SO MANY TIMES!!!), if you are an LEO, name and badge #, and where you work...I need to avoid you folks...you forget just WHO THE BAD GUYS ARE!
