Hoe many cop shows like this?

Southland, Boomtown, and Hill Street Blues all featured uniform cops as well as detectives. So, they weren't exclusively about uniform cops, but a fair proportion of the shows dealt with them.

Car 54, Where Are You? - was a comedy about patrol cops.

SOUTHLAND is mostly about uniformed cops (in south LA) but it also includes a few detectives. In my opinion its the best cop show on TV and well worth checking out. It proves that everyday policing is interesting enough if you tell the stories well but the gritty relentless realism of the show can make for depressing viewing. After watching it, I often found myself wondering what keeps them doing the job - some of the stories are genuinely sad and make you despair for society. It's best followed by a dose of your favourite light hearted comedy!

An old one. George Kennedy in the Blue Knight is another.

Not sure if Beretta counts. I thank he was an undercover detective.

How about SWAT and CHIPS?

Wasn't there also a short-lived bicycle-cop show?

And around the same period, Joe Forrester with Lloyd Bridges started pounding the beat for one season after being introduced on the show Police Story.

It ain't easy being green, or anything else, other than to be me

I really like Rookie Blue a lot....

AND NYC 22 another one they sucked you into watching a really cool show, then without any warning...BAM GONE!

I HATE THAT!

You think I could start a lawsuit charging emotional abandonment with these people that intice you with commercials, encourage you to watch, you watch, you bond with the characters, (I mean some even bring tears to my eyes and that aint easy)then, they say, watch tonight's season finale!!! (Indicating, there will be another season). Then you wait, and wait and wait. Never to be heard of again! How disappointing!

Times that by every show you've ever invested time and emotion in and that's a lot of let downs!
