When Baltimore police sergeant Wayne Jenkins said he had a monster, he meant he had found a big-time drug dealer—one that he wanted to rob. This is the story of Jenkins and the Gun Trace Task Force (GTTF), a supergroup of detectives who exploited some of America's greatest problems: guns, drugs, and hyper-segregation. Shockingly, cops planted heroin, stole hundreds of thousands of dollars, faked video evidence, and killed a homicide detective the day before he was scheduled to testify against the crooked cops. A day of reckoning came, however, and this exposé charts the downfall of the criminal enterprise within the Baltimore Police Department.
