The proposal in the OP of giving the other side the first shot is silly. So is the notion of not using a ranged weapon if someone whith a blunt or cutting instrument is merely over 20 feet away. Make it 20 meters and *maybe *we’re talking, then if you *are *in a position to take the person down with a less-lethal instrument, by all means do so as your first choice.
But I’m not going to demand a suicide pact. Dude with something that looks to a reasonable observer as a weapon, brandishes it around, points it at you? Do what it takes.
ETA: OK, now you are just being utterly ridiculous that even a traffic stop should involve putting the person on the ground, and that even being less than cooperative during a common Terry Stop should contain the risk of being shot to death.
You did not answer the question as to whether he’s squirming because he has been hit with the Taser. I should hope that when someone is on the ground having been zapped or gotten a faceful of chemical, the arresting agents do not feel they have to immediately apply deadly force if he so much as coughs the wrong way. “I told him to put his hands on the back of his head, Sarge!”“Mullaney, he just got teargassed, Tased, and took a beanbag round to the nuts, I don’t think he was hearing you.”
As was discussed in another thread, statutes and cases along the 20th century have essentially established that there is NO individual right to resist arrest no matter what. And a lot of laypeople have no idea what the threshold is for “resisting”, they think it has to go all the way to exchanging punches.
The rise in the level of armed violent crime during the 70s and 80s in turn led to the adoption by LEOs of a policy of rapid escalation, because in our societies people are a risk to reach for something - concealed firearm, concealed knife. So do anything other than total compliance and you may get quickly maced, chokeheld, thrown to the ground and piled on before you can reach for anything.
HOWEVER - THAT is not the same thing as being shot on the spot if you even so much as twitch the wrong way during a common Terry Stop. That is not the ROE of most police forces, either. You are advocating turning them from community police into occupation army.
Given these advisories, the police really should not feel insulted if public figures say “I have to warn my son to be very careful around police”.
