Prosecutors in some jurisdictions report an increase in victim and witness intimidation: some prosecutors have estimated intimidation as a factor in 75 to 100 percent of the violent crimes committed in some gang-dominated neighborhoods. Victim and Witness Intimidation: New Developments and Emerging Responses summarizes recent developments in gang- and drug-related intimidation of victims and witnesses, current responses to the problem by police and prosecutors, and emerging models and strategies for its prevention and suppression. This Research in Action is based on structured interviews with 32 criminal justice professionals from 20 urban jurisdictions, including prosecutors; victim services directors; Federal, State, and local law enforcement officers; judges; and scholars. Also included are the insights offered by a working group of 20 criminal justice professionals, who met in September 1994 to exchange information on emerging responses to the problem of victim and witness intimidation.
