“I say a reasonable police officer (note, the standard for excessive force claims is what a reasonable Police Officer believes, not what a reasonable newspaper reader believes)...”

“But since its a girl it looks worse....had it been a grown man nobody would care.”
It wasn’t a grown man - it was a little kid.
More to the point, if you were on tape using the same moves on your own 15-yo daughter, you would be jailed for child abuse.
If it had been your 28-yo wife, it would have been spousal abuse.
There are different "rules" for cops.
