If I asked you what “CI” stands for, in the context of police work or criminal law, would you know? Almost certainly not. I wouldn’t expect you to.
No, it’s not the name of a new TV crime show. It stands for “Criminal Informant,” or, as they say in the prison system, a “snitch.” It’s the acronym for a known criminal, who the police have coaxed into working with them to land (i.e., arrest and charge) larger criminal targets. Now, most people think that the “coaxing” involved in these cases, usually involves an agreement to “go easy” on a criminal suspect, if that suspect provides police with valuable information on the bigger fish that the detectives have their eyes on: Information such as names, addresses, modes of operation, hidden locations, etc. So, for example, if a suspect is charged with Massachusetts drug trafficking charges, the police department involved might agree to reduce the charges to a “straight” charge of drug possession, for which the sentencing penalties are far less severe (vs. distribution or trafficking.)
But here’s the kicker that most people don’t know: Many Massachusetts police departments and other law enforcement agencies (such as the Massachusetts State Police,) actually pay suspects to not only provide “information” about other criminal suspects, but to testify against those suspects in court documents. Yes, you heard that right. You can get up off the floor now. Some police departments actually pay cash to suspects to provide “information” about other criminal suspects the police have targeted – and inevitably, the “cooperation agreement” the informant signs with the police, contemplates or involves testifying in court documents against those other suspects. In exchange, the informant is not only paid money, but their identity is shielded in court documents, identified only as “Confidential Informant/CI No. 1, (or 2, etc.)”
