Juan Medina has an IQ of 77. Suffice to say he ain't no rocket scientist. Medina's limited mental capacity precludes many potential employment opportunities, but it was good enough for the DEA, which made him a secret agent. It didn't work out very well.

From The New York Times:

Mr. Medina, who had no previous criminal record, said he became involved with the D.E.A. in the fall of 2004, a few months after his father was sentenced to 20 years in federal prison on drug conspiracy charges. He said he was told that if he helped the agency, his father might win an early release.
...

Mr. Medina said he signed a contract even though he told agents he knew little about his father’s criminal associates.

Despite his limitations and the "unremarkable life" he'd led, Medina managed to infiltrate a gang of drug dealers in Brooklyn. Things took a turn for the worse when Medina's criminal associates took him along on a robbery. He claims to have notified DEA of their plans and even waited around for police after the heist went down. To his surprise, no one at DEA would corroborate his story.

The D.E.A. has acknowledged that Mr. Medina, 24, was under contract as an informant. But the agency has not come to his aid, and is, in fact, helping prosecute him on charges of burglary, robbery and criminal possession of a weapon stemming from the robbery at a Bronx apartment. If convicted, he could be sentenced to 25 years in prison.

Whether or not the DEA knew about the robbery, as Medina claims, they bear full responsibility for his actions. They took a man with a limited mental capacity, exploited his love for his father, and sent him on dangerous missions. Their assistance in his prosecution is a rather transparent attempt to cover up their mistake.

This is a perfect example of the reckless abandon with which the DEA operates. Their insatiable greed compels them to create crime and confiscate the proceeds. Sadly, innocent people like Juan Medina are the easiest prey.
