Hey guys, i'm here again. Currently i'm working on a novel, and i'm having a hard time getting the answers i need from the internet. A huge portion of the story will focus on life as a criminal, particularly in a very obscure industry: that of the illegal informant. Although i have the opportunity to communicate with the police, i doubt i will be able to further my research, for confedentiality reasons and all that stuff. So what i'm wondering is basically how this whole information-selling system works, i guess? Any inputs would be great, and i apologize if this whole thread is kindof stupid, i have no clue what i'm doing.
