If the guy cut the carotid or jugular; he’s dead. It’s simply a matter of time.
If the cop shot him after the knife wounds were inflicted; does it really matter why? The end result would still be the same.
“If the cop shot him after the knife wounds were inflicted; does it really matter why?”
Yes it does... We shoot wounded animals (horses) in this country, not people. If the deceased died one heartbeat before he would have otherwise, it’s homicide.
The ultimate in bad government is when it starts routinely shooting the people it governs.
