With the possible exceptions of narcotics, gang, vice and other “sensitive” types of operations, the great majority of law enforcement communications does not — in my opinion — meet the criteria that would benefit from being encrypted.

If there is “law enforcement activity” in my neighborhood, I would like, at the very least, to know what’s going on. I don’t want the police to justify their use of encryption by saying, essentially, “it’s on a need-to-know basis and you don’t need to know.”. Uhhhhh, yes, I do. Its my town, my city, I want to know.

> Yes, and no. Yes, lots of agencies use mobile data terminals or computers in vehicles. They work very well for dispatches and things like license and registration checks. What they don’t work well for is tactical traffic, and obviously not for anything when the officer is out of the vehicle. If you are hearing nothing on the radio channels, most likely they moved to new channels or systems. I can’t give any specifics about Ohio since I am not there.

> To give you an idea how true this is, I run a regional trunked radio system that is used by several dozen cities. Some cities have all city services on the system and some are just public safety. Almost all of the police agencies have mobile data terminals of one sort or another in their vehicles. I just ran a report of the busiest 50 talkgroups for the past 24 hours. Here is a summary of the results:

The reason for this is situational awareness, It lets other units in the area know what’s going on. I can’t tell you how many times that I heard a dispatch, and it was almost immediately followed by another unit (who is closer, but already on a call) say something like “I’ll be clear in a minute and can take that call on xxx street”. Happens all the time.
