After COINTELPRO was dissolved in 1971 by J. Edgar Hoover,[105] the FBI continued its counterintelligence on groups like the Weather Underground. In 1973, the FBI established the "Special Target Information Development" program, where agents were sent undercover to penetrate the Weather Underground. Due to the illegal tactics of FBI agents involved with the program, government attorneys requested all weapons- and bomb-related charges be dropped against the Weather Underground.
