From John Ross’s summary of court decisions in the Volokh Report:
In a “reverse sting operation,” police encourage a target to participate in a fictitious crime and then arrest the target for conspiracy. DEA agents in the Southern District of New York have run 179 such stings over the past 10 years. None of the targets have been white. All but two of the targets have been black or Hispanic. District Court: That doesn’t sound like a coincidence. Defendants are entitled to limited discovery about why they were targeted. (Click here for some journalism.)
P.S. Among all the federal law enforcement agents, the DEA is known to be the second stupidest.
