Force of this nature is only appropriate if the person constitutes a danger to himself, or others. This child did not. In addition, a cop should never act out of anger, which is what this cop did. The cop could have permanently injured the girl, who was passively resisting. (In fact, the cop almost injured the kid sitting behind her). While she is obviously a problem child who should be removed from the school, there are many other ways to do that other than by tossing her around the room like a rag doll.
Passive resistance is injuring the rights of others.
That you are under the impression that passive resistance must be met with passive opposition, doesn't alter the inevitable fact that passive resistance is only valuable to the point where passivity gets your ass kicked.
FACT: No student in that classroom, will be using THAT method again, EXCEPT where the powers that be EMPOWER the resistors by removing the one individual that settled the issue.
Now... what you're advocating here, is to lower the standard of behavior.
This can, and will only, result in lower performance, thus encouraging more of the behavior which caused the problem. The COP is NOT THE PROBLEM.
The only reason that the Cop was there, is that Schools stopped allowing TEACHERS to do their job.
That kid and that attitude would never have survived the individuals running the schools I attended.
In my world... had I behaved as that kid did... and had that cop done to me what he did to that kid... when my old man got home that night... what the cop did would have been a PARADE of Ice cream and Cake, compared to what my Dad would have done to me, that night.
Reader, what you see in the above cited response, is what is OKA:
THE PROBLEM!
