Cops can handcuff you when/after interacting with something.
Ofc Bulldozers are an exception because it would be too much overpowered, also snipers and cloakers cant handcuff players.
They cant handcuff you on swansong, and the last player not in custody cant be handcuffed.
You can play this mod on solo without bots since you are the last player. Mod inspired by IREnFIST - Reloaded mod
