Not sure what you mean "strict standards of who can attend"? If you pay the tuition you're in, Jews, Protestants, anyone.Tighter security.
Strict standards of who can attend.
They have strict standards of who can attend, it is not just about money. Grades. Discipline issue. Learning disabilities. All can be denied attendance to their schools.
And perhaps, "all" contribute to dodging the types of problem kids that turn into shooters?
Of course they do. Public schools are not allowed to do those things.
Seems kind of a quick jump. Is it all of them, or just three of them? Can we learn from this and apply a lesson to make public schools safer?
