The no weapon policies are the result of lawsuit happy parents. Little Jimmy punches your kid and you find out that he has had an issue of guns and ammo in his locker. Guess what we get, hours of lawyers and social workers looking to see if we are the next Columbine or VT. Talk to the bean counters not the teachers.
Kid ODs on Tylenol and gets liver damage, lawyer finds out some kid at school gave it to them. We get sued. Again not the teachers fault, go talk to the bean counters down town. I have had kids OD in my class on over the counter drugs. It is surprising what some people will take and what it will do to them.
As for nail files there is no reason to have them in school, and yes I have seen them used as weapons nasty little buggers. Might as well let boys carry straight razors.
People that blame all the problems they have with public education on teachers have not seen the issues from our side. Come and do my job for a year and then tell me how the NEA or other teacher cabal is running the schools. You would be shocked to see how little power teachers really have.
The men and women in black robes are the ones that run our schools.
The men and women in black robes are not the ones segregating Lamcaster, though.
