Last month, Mayor Bloomberg sued City Council over a law that would make it easier for New Yorkers to take legal action against the NYPD if they believe they’ve been profiled. Now, the city’s biggest police officer’s union is getting in on the action.

The Patrolmen’s Benevolent Association is arguing in a suit that the law “‘leaves officers to guess’ what’s allowed and threatens to taint the entire New York Police Department with a brush of discrimination,” according to the APCity council says they’ll “aggressively” fight the PBA’s lawsuit.

It’s unclear to me why the NYPD is so riled up about the new law. According to their own logic: if you’re not doing anything wrong, what do you have to worry about?
