The main problem with parents is they don't get involved enough. A friend of mine is a school teacher, and he told me that when they break up fights in the hallway, if a student hits him, he's not allowed to hit him back. All he can do is block the punches. He's not even allowed to wrestle the kid to the ground.I don't blame some teachers for leaving depending on the school district & their regulations.
Too many lawyers, laws, public school boards & parents are watering down discipline, dress codes, & some times even curriculum.
Now we had fights in the hallway in my day, but if you struck a teacher, you are going to feel it for a long time. When the teacher yelled "BREAK IT UP" you threw your last punch for the day.
