I'l put $10 on "All of them"
Well, according to virtually every university police chief who has spoken up against TX HB 1893 (campus carry) last session, all of their officers are trained to kill 'em all and let God sort 'em out when it comes to armed people in the vicinity of active shooter situations.
Anybody want to gather up a few folks and a video camera, and just make a basic "shoot/don't" walkthrough video with this scenario? Start out of view of the incident area, with audio of a single weapon firing 20+ shots. Camera enters the view area 3-5 seconds after the last shot. Cut to black, say, a half second (representing time to decide during draw and aim, as well as how long you would have before a still-armed psycho would shoot you if that were the case) after the camera rounds the corner into view of the bodies, the armed, probably extremely jumpy person, and the dogpile on the (actual) shooter, and attach it to a poll. Best to dump it in the middle of a bunch of shoot/don't videos, though, so the viewer doesn't go in with this incident already playing out in their head.
There are a few things it would be helpful to know, though:
- How was the man holding the Glock? (Was he even holding it by the grip? How noticeable would that be on first sight?)
- Where was it pointed?
- Was the slide locked open? (Since the shooter had run dry at the time, it might have been. Again, how visible is this from the CHL's point of view?)
- How was he dressed? (Gangbanger, average guy, nicely dressed enough to be plainclothes security, wookiee suit and saucepan helmet, etc.)
