A Kentucky jailer up for reelection was secretly recorded using the N-word in racist, sexist phone call

The operative word is “could”. You can only prosecute people for their actions, not their opinions. If he leverages his beliefs into official decisions, get him. The second he misallocates resources based upon race instead of evidence, kick his ass. But until then, it doesn’t matter what he thinks - it matters how he behaves. If you throw people in jail based upon what they think, they’ll happily do the same to you.
