Twisting an arm or a leg to cause serious injury after a play is way worse than a dirty hit during an actual play.
high school athletics should be over completely for a player if 100% indefensible video exists.
if it was my kid on the receiving end of something like that I would lawyer up and file lawsuits against everybody ( player, school, state )
I was at a small class HS game earlier this year. It was early in the 4th, and the game was starting to get chippy.
The home team had a big lead at half, but was getting frustrated because they kept getting called (correctly btw) for penalties, several of which took points off the board, and the other team kept scoring to keep the game interesting.
So things started carrying over through the whistle on many plays. Coaches were chirping at the refs, players were chirping at the refs, even the home team's PA guy was getting snarky in the booth.
The tackling started getting a bit rougher and lower on the body. Eventually, the refs just started throwing PF flags for any little thing from either side to try and restore order.
Unfortunately, the worst thing I saw ended up going unnoticed by the refs despite it being out in the open for everyone to see.
The visiting team hit a big play that got them inside the opposing team's 10. The kid with the ball, just a freshman, was caught from behind by a senior from the other team, and even prior to what happened next, you could see the frustration from the players for giving up big play after big play to the visiting team (which was still down by 14-21 pts at any given time at that point).
The older player tackles the kid that made the catch, rolls him up from behind, then aggressively drives him into the ground and then while still pinning his body on the back of the kid's leg, begins driving his shoulder into the back of the kid and even pulls his leg back to try to injure him.
And sure enough the kid came up limping off to the sideline after the play. The refs were the first there, but apparently didn't feel what they were seeing was excessive enough to warrant a flag or an ejection.............
