I find nothing wrong with the rules so long as the kids know about it. If the kid was given a student handbook and had to attend a mandatory session explaining either school rules or where they can be found (of which every school I know does this) then he has no recourse.
Schools are a place of learning and socializing. Hug and kiss on your own time. I'm not against hugging and kissing, but people need to learn some self control. If it's not allowed one place, but everywhere else then they need to learn to wait to do what they want.
Zero tolerance policy stupidity not found here.
I thought this would be like my zero tolerance stupidity I ran into when I was in highschool. Now my scenario was true ZT stupidity. I had a kid attack me out of the blue. Someone I didn't know and I was minding my own business. Just struck at me. It was all caught on camera and witnessed by several teachers. Despite that, I was still in a "fight" and was suspended for 3 days because of it. Almost expelled like the other kid all because I was attacked. If it wasn't for the cameras, teacher witnesses, and my parents threatening to sue the school I would have been expelled. Now THAT is stupid ass ZT policy.
