During the last 20 years, police have killed at least 40 innocent people while conducting wrong-door raids. According to a study by the Cato Institute, "Because of shoddy police work, over-reliance on informants, and other problems, each year hundreds of raids are conducted on the wrong addresses, bringing unnecessary terror and frightening confrontation to people never suspected of a crime."Here's a link to the Cato Institute raid map. Fitzgerald goes on to identify the problems that lead to such raids, including:
1. Willful disregard for police standard operating procedures governing the use of informants and conducting controlled buys
2. Use of "cookie cutter" affidavits containing boilerplate language from a computer program
3. Blatant lies in search warrant affidavits
4. Creation of phantom informants
5. Supplying drug exhibits "purchased" by a phantom informant
6. Planting drugs in homes when no drugs are discovered during a search.Fitzgerald is also the author of the book "Informants and Undercover Investigations: A Practical Guide to Law, Policy and Procedure" (CRC Press, 2007).
