As protests over police brutality continue across America this week in the wake of George Floyd’s death at the hands of former Minneapolis cop Derek Chauvin, popular reality shows chronicling — and often lionizing — police activity, like “Cops” and “Live PD,” have been sent to the slammer. Scripted series about law enforcement agents have been a mainstay on television since the black-and-white days, but they’re not exactly a dominant genre on the broadcast networks this season.
