Reserve Deputy puts one through the passenger door of a stopped vehicle. Follow up article here. I think it serves as a good training video and subject for discussion.
From my amateur observations he appeared to have way too many things going on at once... It reminded me of Darryl talking about running on the ragged edge at 110 MPH and not being able to process everything going on. Possible sympathetic motor response while going for the door handle? Why not try the door handle before smashing the window? Is it taught as a technique to distract the driver or just an oversight?
