IMO death penalty.
I'm against capital punishment except for politicians, law enforcement, and wealthy elites, specifically who used their power and authority to subvert attempts to bring them to justice. A person like that is unlikely to be reformed and even less likely to turn around and become a net benefit for humanity.
They shot 1 healthcare CEO and how many people's lives were saved?
Maybe we give 1 bad apple the chair every quarter and see how that improves policing.
