Everytime I've been busted it was from a confidential informant. A snitch, not a cop. Someone close to me got busted and rolled. Thats the way it works around here. I think any of the judges that I've been in front of would have got a good laugh out of the signed paper. At best it might keep the people who are to wigged out anyway from signing. And I dont think a law enforcrment officer can break any laws, that is called entrapment. Now a snitch can do anything and everything up to and including fucking you in the ass.
