For anyone who hasn't seen the episode, it's about a rich white guy using his money/power/influence to kill people and go unnoticed, hiding in plain sight.

Quote from the episode:

(context: talking about who the criminals who commit serious crimes are) They're always poor and lonely and strange. But those are only the ones we catch. ... What if you were rich and... powerful and necessary? ... What if you had the compulsion to kill and money? What then?!
