Before George Floyd's murder, I'd seen some debate on Twitter about how unrealistic Brooklyn 99 was, how progressive all the characters were even though a supermajority of cops are Trump supporters (this was partially tied to a debate of how unrealistic the Michael Schur workplace sitcoms have always been). At the time I had mixed feelings, because I thought - well, it's just a fantasy, people know it's not real life. After the last week, and other stories (I think this was already posted here) like the one about the L&O writer who was tweeting about wanting to kill looters, I realize the shows are a real concern and should be addressed.
I think we will see a fade of some (probably not the Chicago PD/Fire/etc. series) and then they will return in a year or two under the umbrella of some kind of "good cop against the system" banner.
Watching the John Lewis interview, I can't imagine how he's feeling and what he must be reliving.
