I got the camera when I was doing dedicated DUI enforcement. Then all of the cars started getting them. Ours only record when the overhead lights are activated
Do you turn the camera on them for the ride to jail? I had a few clients where I thought they did pretty good on the field sobriety exercises, then they're so pissed off about being arrested, they go ape-[bleep] in the back seat and there's 20 minutes of the most god-awful cussing and swearing.
Not something you want the jury to see.
