This kind of cr@p keeps coming up over and Over and OVER again - it's been decades years since I read about a case where school officials tried to stop a physically handicapped schoolgirl from reading her Bible ON THE FREAKING SCHOOL BUS going to and from school. They got smacked down then, but it seems they have to KEEP getting smacked, again and again and again.
It's about time the bureaucrats involved were PERSONALLY made to pay the financial costs of any and all court proceedings - given the long history of this sort of thing, simple ignorance is no longer an excuse; this has happened so often that malice is the most likely motivator for continuation of this practice.
