In the criminal justice system, the people are represented by two separate yet equally important groups: the police, who investigate crime, and the district attorneys, who prosecute the offenders. And sometimes the police arrest the former district attorneys for dealing drugs. This is David Leung's story.

According to police Leung, 44, was busted by an informant on September 27 after he slipped the undercover agent two bags of weed for $200 on Ninth Street (they'd already agreed on the deal over the phone). After the exchange police say they found seven more bags of pot, totaling more than eight ounces, in the trunk of the car Leung was driving.

What makes the routine bust of a pot dealer in the marijuana arrest capital of the world interesting, however, is the fact that Leung was recognized by a defense attorney and some arresting officers when he showed up at court yesterday—because he had been an assistant district attorney in Manhattan from 1993 through 2003.

After leaving the DAs office Leung reportedly went into private practice and moved to Indiana—but seems to have decided there was money to be made on the street. Yesterday in court Leung was told "he had not yet been indicted and set a return date of Jan. 22 for possible grand jury action." In the meantime he remains free without bail.
