sorta unrelated, but maybe not.
There's a YouTube channel called "Live On Patrol" based in Ramsey County
it's sometimes funny, and sometimes actual crime!
The LEO (Sheriff or under sheriff, don't recall) riding with a civilian employee in a unmarked suv with lights and siren
They're more like stringers lol They show up on calls but for the most part just make comments about what you're seeing.
(Probably the object of the channel)
Sometimes they are actually LIVE on YouTube
THE RADIO TRAFFIC ( I knew this was related somehow lol) can be heard in the background and sometimes the LEO guy explains unit callsigns
How to tell what city, patrol type, etc.
Anyway, though it was worth mentioning for those who may not know.
