Just curiosity mind you, but I wonder what caliber and bullet type they were using.

The perp by the window (ex-window) looked to have a significant bleed out.

Must have been a big hole.
Or a well-placed shot.
Or both.

Yep - the way it spurted when he collapsed, they hit an artery. Nice shot.

The guy in the white shirt gets shot again, after he’s down. It’s at about 0:55 on the video. Shot enters his right abdomen. He was moving around, trying to raise his head, when he’s hit for the last time.
