Eleven months after his incarceration, Barnes telephoned Federal prosecutors indicating that he would agree to become a government informant in their case against Fisher and others. Barnes claimed that he decided to testify because Fisher was having an affair with his mistress. In exchange for his information, Barnes was released into the federal Witness Protection Program.
The passage describes Barnes' decision to become an informant, driven by personal motivations (Fisher's infidelity) and facilitated by the government's Witness Protection Program.
