I feel the same, my partner doesn't arrest people, he kills them..
I was on a callout about homeless people. When I'm talking to the homeless people and asking them to leave, my partner pulls out a gun and kills the poor guy.. WHY!?
He did this another time too, but this time he killed himself. So we were done arresting a suspect, and on our way to the car when my partner suddenly pulls out a rocket launcher and blows himself up. I didn't quite understand what happened...
So for my own safety I have started to do most of my patrols alone.
