Isn't this another good reason why corporal punishment on kids doesn't work (what if they hit you back)?

On this video a mother had a horrible argument with her 17 year-old daughter. At some point there were exchanges of words and since she's a Mexican woman relying on hitting and pulling hairs, she threatened to slap her. The daughter replied that she would hit her back. She was daring her to do; thinking the daughter wouldn't reply back. The daughter hit her back and the mother cries, playing victim. The teen obviously doesn't feel remorseful? Why should she? I hate it when the cop tells me that until she's 18, she has to tolerate the rules, even allowed getting hit a bit as long as it's reasonable just because spanking is still allowed in that state and that's her mother.

I actually don't feel bad for the Mexican mother. She got physical first and got hit back in return.

She raised her daughter by installing her that violence is ok to use if you can't get your points across, that hitting is the only way to make someone listen.
