> Society would feel more free if every police officer's DNA was stored in nationally searchable database and indefinitely retained. Would it? Usually the criticism I see of police is that they protect each other even when there's clear evidence (e.g. a video) of a police officer committing a crime. Police officers already have plenty of technical ways to investigate each other, but what good is that if evidence of misconduct is buried or they refuse to arrest each other?
