How to disable Arrest batton and unarrest batton in darkrp ?

What do you mean by disable? If you don’t want police to spawn with it then you can simply remove it from their weapons. Go into the game modes folder, then darkrp, gamemode, settings, then edit the job related file. This is where all the default teams are defined. Just remove the arrest and unarrest batton from the teams that have them.
