I agree with bryanvincent. the most obvious meaning would be police..possibly police brutality? (patience not a virtue) he's talking about how police are cowards but they feel powerful behind a badge and a gun. Maybe he fucked up an officer (see its a joke for me, 3 years in the hole for me served everyday laughing at all of you). You are supposed to be able to trust police, but some are just bad cops (trust is a knife in the back trust is a bullet through the head)
