Actually, the problem is that she doesn't think, she feels and mistakes that for thinking.
Agreed. I think it's pretty clear that the exception was included to allow security for schools. Who cares if that person also happens to already be on the payroll, serves another purpose, AND doesn't cost the taxpayers anything extra? Win win win?
If she has the stance that security isn't allowed to be armed (which is allowed by law) then she should also hold that police shouldn't be allowed to have weapons on school property either.
