I'm sure if a teacher shot a lone, adult attacker that was unknown to him/her, it wouldn't be an issue. The problem would arise if a teacher had to shoot one of his/her own students. It doesn't take too much of an imagination to see where that story can get twisted from it's original plot line by the time it reaches the public's ears by the media. You would need every ounce of the law on your side if you were ever in that predicament, as public opinion and street justice would be set firmly against you.KBCraig wrote:PC 9.51 justifies using force or deadly force at the direction of a peace officer. I have to believe that courts would find in favor of anyone violating CHL laws at the direction of a peace officer.
As a side note, most of the students in public school are a pleasure to teach. The vast majority will behave appropriately and will not committ violent acts against others as long as they are taught right from wrong. You're always going to have a sociopath, regardless of the institution, nation, or time period, and in spite of your best efforts.
