On a battlefield, both heroes and fools will leave their defenses and move forward when ordered to do so. The difference is that the hero knows in his heart that he may not survive it but does it anyway.
I'm with Sunny on this. At least a few of the Cops at the room should have been thinking "I just can't stand here and let this nutcase keep killing my people- I have to stop them even if it might kill me." but apparently not one of them had that in their heart. If all that the Cops are going to do with their guns is point them at people who forgot to use their turn signal and to shoot unarmed people who are deaf then they should not have guns because they are not using them correctly.
If the door in question is he one shown in the pics, that's not 200 rounds gone through it, probably not even 20. It's also the 'fixed' door of the pair, not the one with the handle you'd open first to go through there. The door wasn't in that position during the action; look at the holes and you see some where the other door wasn't even nicked where it should have been if it had been that way during the shooting. And yes, the cart could have been rigged, but in that hotel was sure to be a mirror to let the Cops look around the corner without exposing themselves, a cellphone cam which every Cop on the scene had could have been used similarly, another cart could have been quickly shoved into it from around the corner to upset it's position and test for traps, a painter's pole used from the maintenance room to shift it from where it was, or a blanket thrown over it once they saw in that mirror or phone screen that there was a camera on the cart.
Something could have been done, but instead the Cops did absolutely nothing except to call for SWAT because that's what they are trained to do. And that is where the point of failure begins. Their improper training is endemic in the system and it's wrongness is what lets numerous innocents get killed and allows nutcases to kill for 5 more minutes when there are better ways for things to be done. We must demand that their trainers be relieved of duty and be replaced with sane intelligent people who understand that being a Cop is an inherently risky business and that sometimes they are going to have to greatly risk their own lives for the good of the people whom it is their duty to protect, for that is their job- their job is not to save Cop's lives only- and the people have every right to expect them to do it to the best of their ability.
I'm unwatching this thread again as things like this only serve to anger me and I'd rather not see constant reminders of what my once great Nation has become in my lifetime. I'll read the thread only when I can handle it.
