I feel your pain, only worse. I am a public school teacher.
Every day is a bash-o-rama here on FR.
Some public schools are pretty good.
I guess it depends on the city, or part of the city.
We moved where we did because the schools were good.
Back on subject, If the perp was spotted its a matter of time before the ycatch him hopefully.
He is no hunter of wild game.
You have my sympathy. You are really behind the 8 ball.
However, my attitude as the father of a now adult home schooler, is not to look down upon, or berate parents of public school kids. I have known a lot of kids that would have been much better off outside of public school and I regret that they were not as fortunate as we in being able to do it. Some parents could have made the sacrifices we did, but many could not, no matter what they wished.
My opinion is that in general, the public school system is so flawed that substantial improvement would require change of a magnitude that just will not happen in the foreseeable future.
