if YOU are a cop, and you stumble upon a report of TWO intruders, as the 911 clal showed...
and you only walk in and see ONE man..
you're going to get the first guy out to ensure the 2nd guy isn't in the bedroom with a shotgun ready to ruin your day.
They had a called telling them there were TWo intruders - listen to the 911 call - they thought there was a second guy. And this was a high break in neighborhood.
police 101, and I bet kh300 backs this as well. If you think there are two bad guys, you don't interview one in the house with unknowns in the rooms. You take 1st guy outside for an ID and then you look for a second guy.
And, if guy #1 starts screaming shit about your mama.... and you don't know who is in other rooms, you certainly cuff his ass and put him in the car.
Of course, most of you are some slipping ass fools who would have sat down in the kitchen and checked out IDs while bad guy #2 could have come out of nowhere. The cops were told 2 bad guys, and they did the smart thing.
