According to the reports I’ve read, The FBI HRT had the boat surrounded, and they were the ones who engaged in the firefight with him..How he isn’t dead is hard to fathom.
Dummy rounds... they wanted him alive. They got him to use all the rest of his ammo so they could get him out of there.
My understanding is they didn’t want him dead. Reminds me, in a way, about the dog that chases cars: Now that you caught it, what are you going to do with it?
Says something about marksmanship.
Was not a firefight, they simply talked him out.
