And American cop shows bend over backward to virtue signal "diversity". Yuck. So transparent and facile.
I just feel like the American shows are always trying to rub my nose in something. There is less of that on the British shows.
The one thing I have noticed about a lot of the British cop shows is that the higher-ups, like the Commissioner, or their immediate subordinate are always in a big hurry for the crime to be solved, and somebody charged, especially if the case pertains to murder. They seem to put a lot of pressure on the DCI's and D.I.'s and below to find, and charge someone. About the only program I haven't seen that happen is in the "Vera" series. Since they most likely use members of law enforcement to advise them on those shows, it's makes me wonder how much of that goes on in actual police murder cases.
