Children are, in effect, risking their lives by attending school.
Fatal attacks from deranged students are spreading like an epidemic. When I was a teenager in the 70's, high schools had some problems with drugs and racism, but there was still a remnant of respect for teachers and school property. Not so now. Police are a common sight on school grounds, anti-drug campaigns are routine even in elementary schools, kids bring weapons to class and actually kill innocent people. Children aren't able to concentrate in such a threatening environment.
