I like what you say, Jonty.
“You can sit from him, after having called the cops and, if he then moves, blow him away.”
The problem with this situation, is proving it later.
I can see your point on this and normally, you’d probably get a slide on this, if you lied well enough. :)
Howver, it was clear in the video the perp was no threat under any circumstances and that’s the difference.
