Undercover cops are a terrible idea, amirite?
they don't protect or serve anything. they just catch people AFTER the crime is done to punish someone rather than actually preventing crimes and keeping people safer. their existence is borderline entrapment. If something meant to protect people has to hide from people, it's probably against people. Imagine having an undercover boss who didn't supervise or guide you, just hid and waited til you made a mistake to fire you.
