If LEOs are needed at schools today- then get them in there and let them do the job. School officials need to be worrying about doing their job- they haven't been doing such a bang up job of educating the students so they just don't need to be expanding their job into other areas.
If you're saying the school should change their policy, allowing students to exchange (legal) drugs with each other in the hallways and classrooms, speak up. Do you support that?
