The Anti-Cop-Radar is a potion that makes you unlocatable after use on the Map, the Compass and the scoreboard of the cops. If there is a bounty on you, your position isn't shown on the map anymore.
However, usage is a criminal action which gives you 45 crime.
The item of the anti-cop-radar is a thick potion.
The texture of this potion isn't affected by the Crime Texturepack.
Usage is very simple. To activate the anti-cop-radar, just hold the potion in your hand and right-click.
The anti-cop-radar can be bought at the Secret Shop for 10$ and is only available in this particular shop.
As no shop buys that potion, you can't just sell it to a shop which of course doesn't exclude trade between players.
