The part where he was nowhere in the proximity of the shooting and didn't even know what building the shots were fired in.
Did you bother to click on your own goddamn link or do any kind of research on this? If you had you would know that Building 12 (or 1200) is the building where Cruz did all his shooting. You would also know that Cruz entered Building 12 at the east end and, more importantly, Peterson arrived about two minutes after the shooting started outside the east end of Building 12 where Cruz entered.
As the shooting is transpiring, Peterson realizes the shots are coming from this building. He is on audio reporting shots fired in the vicinity of Building 12 and warns other arriving officers to stay 500 feet from Building 12. He then retreats to a spot on the northeast corner of Building 8 where he can see the east end of Building 12 and then just stands there.
Two things here:
1.) Peterson knew two minutes into the shooting that the shots were coming from inside - or the vicinity of - Building 12 and said as much on the radio.
2.) Cruz would continue to shoot for another four to five minutes as Peterson stands outside Building 12 (knowing by now that this is where the shots are coming from) and does nothing.
No, it's not. Peterson didn't stand there and do nothing because the gun industry sold Cruz an AR-15, he did so because he's a coward.
Cops shouldn't have to face people armed like soldiers.
And yet sometimes they do.
The rationale you RACISTS use to justify every cop who shoots a scary black man is "He feared for his life".
Not every shooting is justified and I understand this. However, sometimes an officer legitimately fears for his life and sometimes he is right to do so, given the number of officers being ambushed or having seemingly harmless suspects suddenly pull out a weapon and start shooting.
Well, here you had a pretty reasonable concern that you had an unknown number of assaliants in an enclosed area, with a lot of bystanders, and he didn't charge in until backup arrived.
Hindsight is always 20/20.
Right, and our 20/20 hindsight shows that an untold number of kids were killed because of his inaction.
Really, the gun didn't magically fall from the sky. Someone had to fabricate it, ship it to a store, and sell it to him.
The gun industry didn't sell Cruz the gun, the store did.
