Given that Charlotte-Douglas Airport is a worldwide leader in security theater — what with the body scanners and all — I guess it stands to reason that the busy-bodies at CMS would get into the act. Drug sniffing dogs at schools are a waste of time and an anti-education distraction.

Quick, tell me what part of the school is the sole property of a student? If you said lockers you are a fool. Wait, backpacks. We are actually going to sniff backpacks for drugs? Everyone’s backpack. What a great use of time and resources. And this assumes that drug dogs work.

Care to hazard the false positive rate for drug dog “alerts” — try anywhere between 12 and 60 percent. “Sweeping” rows and rows of lockers with drug dogs — the usual security theater skit performed by clueless school administrators — is a guaranteed disaster with even a 10 percent error rate. Get ready for some Honor Society gal to get frog-marched out of a CMS school because her dog at home is in heat. Cue massive lawsuit.

But CMS does not care. It is all about appearances. We are going to appear to be tough on drugs, nevermind any teacher can tell you straight away who is probably dealing. It is probably the kid with multiple arrests already. And CMS does not care about getting sued, as its serial madness on funding charter schools proves.

Reach further? No kidding.
