S7E4 Disgusting Slander of a good sheriff
It is clear who the sheriff in this episode is meant to represent; he is an Arizona sheriff who uses prisoners on chain gangs, & has them dressed in pink jumpsuits. Sheriff Arpaio is famous for dressing his prisoners in pink and making them work. And the leftists hate him because he upholds the law, including the law regarding illegal immigrants.
So the wonderful Hollywood writers decided to have a sheriff who does some of the things Joe Arpaio is famous for, and they decided to make him a murderer who killed a prostitute he had sex with.
It is a good thing this show was cancelled not long after this episode aired.
