Yeah - but if the story is correct, these guys were not responding to the 911 call. They heard the invasion on their own (???) And were responding on their own, not to the call?
Sure... absolutely if you make a 911 call about a home invasion, and you are armed, you should disclose that. My brother actually has a rather amusing story to tell about that, but in this case, if the telling is correct, it’s as if there was no call, the cop in the room only had what his eyes could see to guide him.
The bit about the rather bizarre handling of the injured homeowner doesn’t make any sense. So much that I wonder if that part of the story is actually true, or maybe there was something different going on. Put him on the hood and drove down the road? I’m just not buying it...
I agree that the key mistake here was not passing along the essential tidbit of information to the cop making entry— that the homeowner already had the perp and was holding him at gunpoint. That cop really needed to know that. Could he have handled to situation differently anyway? Maybe, but those decisions are made in nanoseconds and we don’t really know enough to say.
