So they had a basic fear of being heard and not being able to c.t.a., and no legit reason to encrypt all comms, so they used the ones that 4-8 commissioners can simply understand, with tons of unintended consequences. If good police work trumped 12 listeners they might be a better department, instead they lost valuable community assistance and oversight. hopefully the ebb and flow will change the other way, (and hopefully not caused by a tragedy). 4 criminals with 4 cells phone can overcome encryption any day, well in-fact the 4 cell phones have encryption but that's beside the point.
