Basic handcuffing techniques include various wrist locks, armbars and strikes to major muscle groups to induce pain compliance. A choke should be reserved for when lethal force is justifiable, but using the firearm isn't. The police in this scenario escalated the situation and used a lethal technique (which isn't even taught in that agency) when it was not justifiable to do so.
Was the subject viscously curb stomping someone? No, a choke was inappropriate and excessive; it is never taught as a control technique for that level of resistance.
So you're saying that they should have beaten him in to submission instead?
What I'm saying is that if you can't do the time don't do the crime.
If you're an asthmatic you really shouldn't be selling cigarettes and if you've been arrested 30 previous times over 30 years you really should be somewhat familiar with the police handcuff procedure, as they apparently let you go 30 previous times.
