They were showing re-runs of Barney Miller on Antenna TV or one of those similar channels. All time classic. The 12th Precinct is the same one that is used for Blue Bloods
I don’t think I’ve EVER seen re-runs of Barney Miller. I would certainly watch them if they were offered. I see MASH re-runs, but Alan Alda makes me want to punch people, so I don’t watch.
