they gave him plenty of warnings, wouldn't even get that much leeway here. Should have popped him the first time was reaching
Itll be boiled down to the 2 seconds where he stopped moving and said "I'm not reaching" then the gun went off. Cue riots and people printing out tshirts. Nevermind the two dozen warnings or the half minute fighting on the ground reaching for the gun multiple times or fleeing in the first place or having the gun in the first place.

They probably didn't shoot right away because they know there'll be investigations and any use of force in Seattle you have to go before a citizen review board and all this other shit. Trust me it was the last thing any of them wanted to happen
