I staying out of the "freedom" argument. If you polled 50 people about it, there would be 60 opinions. Let's just say what they're doing is legal and there's nothing you can do about it. If you think it's wrong, it's a Constitutional issue so take it up with the U.S. Supreme Court.
Anyway, there was quite a bit of unencrypted traffic in the Columbus-Muscogee County public safety talk groups this morning. It was the Metra parking enforcement. Downtown parking is handled by Metra Transit and they apparently have a channel in the CSU police group. The only dedicated parking "enforcers" are Metra for the downtown area. (Metra is the public bus system and why the powers-that-be saddled them with that is beyond me but that's for another thread.) Anyway, there are many different facets of CSU in the downtown area including music and art schools, public performance facilities and housing. They even own the convenience store downtown. There are more campus police in the downtown area than city police for that reason. If calling for help, a campus police officer could probably respond quicker. CSU police talk group transmissions are not encrypted.
