Whoa!!! Looks to me if anyone took any shrapnel, it was her fellow LEO who was getting ready to handcuff the guy.
I don't have sound at the moment, but it looks to me he had said something to the effect: "Point that damn gun away from me."
"BAM"
I think he may indeed have had something hit him. It made him forget about hand cuffing the guy and stand completely up and forget about the guy. Hell, I guess I would have levitated a few feet over the guy due to, well let's just say it wouldn't have been a clean underware day.
However, watch when he goes back down to one knee to hand cuff the guy again. He holds his right hand out striaght, and still doesn't grab the guys hand behind his back. I think he was still looking back at her thinking, "Holy shit! I'm still alive! YOU $%@#ing %#$@*!!!".
The perp on the ground looks like he is actually contemplating an attempt to stand up just to go over and kick her ass!
Thank God no one died!
