If the sixth-grader knocked him to the ground first (did they say it was on video?) then it’s self-defense.
Holding her down with a knee also kept his hands free to defend himself against any others that might want to attack him.
One of these days a cop won’t even be able to grab a person’s arms to put them in handcuffs. (Torn shoulder ligaments.)
When they came for the choke-hold I did nothing....
When they came for the knee restraint I did nothing....
“If the sixth-grader knocked him to the ground first (did they say it was on video?) then it’s self-defense.”
If that same cop would punch your ticket for doing what he did then it is not self defense.
Looked like a buffalo heifer to me instead of a 12-YO girl.
