Those Cops deployed their police cruisers remarkably well given how many there were and how suddenly the chase was over, didn't see any Cops almost get hit getting out of their vehicles either. Is that something they also train for?
Yes.
Stopping a car when your co-worker is in front of it is something they train for.
Not sure if that was sarcasm or not, but that open fan shaped pattern also leaves lots of cover if the perp comes out shooting, like that guy who hijacked a UPS truck a few months back.
