Again, your opinions are interesting, but fortunately the laws disagrees with you.
Yes, people can die from tasers (p.s. tazer is actually a brand), but people can also die from pepper spray and being hit with a purse. However, it is rare. Taser related deaths have only occurred due to other physical ailments/complications. Please do a little research on this. Also, he could have grabbed her and forced her out, but that would have likely led to more injuries on her than tasing her.
Failing to follow a lawful order is a violation of TX law. Using a taser is authorized by TX law in a situation of passive aggressiveness. It is not a violation of any rights. SCOTUS has already ruled on it.
BTW...your persistent implied threats about shooting a cop only prove you to be a coward. I say “bring it on”!!
