Stop Defending Yourselves, New Yorkers! The city prosecutes another case of subway self-defense.

Last week, while riding a northbound J train through once-posh Williamsburg, Brooklyn, 20-year-old Jordan Williams and his girlfriend were accosted by Devictor Ouedraogo, a 36-year-old ex-con who had served three and a half years in prison for an attempted robbery. After completing his term, Ouedraogo was released to the custody of the Immigration and Naturalization Service (INS), suggesting that he is or was an illegal immigrant.

According to eyewitnesses, Ouedraogo was verbally and physically harassing other passengers in the subway car before approaching Williams and his girlfriend, who remains unnamed and has not commented on the incident. After Ouedraogo propositioned his girlfriend, Williams verbally warned him to back off. Ouedraogo allegedly responded by punching both Williams and his girlfriend in the face.

In what sounds like a legal exercise of the right to self-defense under New York law, Williams then reportedly rose to protect himself, his girlfriend, and others from Ouedraogo, who fought back. During the altercation, Williams pulled out a pocketknife and stabbed Ouedraogo, who stumbled out of the subway at the next stop. He received medical attention but later died at a hospital. As with Jordan Neely, the homeless drug addict with a criminal record who died after being restrained in a chokehold by Daniel Penny last month, no autopsy of Ouedraogo has been released, fanning speculation that the results could indicate serious drug abuse.

Williams and his girlfriend continued their subway ride, but NYPD officers apprehended them at a station down the line shortly afterward. Williams was arrested and charged with manslaughter and “criminal possession of a weapon.” (Knives are forbidden on city transit, though this has not stopped knife incidents from increasing 126 percent over last year.)

The Brooklyn district attorney’s office wanted Williams held at Riker’s Island on $100,000 bail, an impossible sum for him and his family to pay, but last Thursday a judge released him from custody without bail, in part because his employment record at FedEx suggested that he was neither a career criminal nor a flight risk. Unfortunately, FedEx fired Williams the next day, showing little interest in the facts of the case or in now-quaint notions about the presumption of innocence.
