A phrase of Ned Kelly origin, that refers to police officers. The police of the times were characterised by thier jackets, which are notably absent from the uniform of today. Kelly was notoriously a hater of the police. Putting on the jacket refers to enroling at a police station.
By putting on the jacket, one signs themselves up for hatred from the criminals of the world.
