Back in September 2009, the FBI and NYPD raided Queens homes because of a plot to bomb the NYC subway system. While suspects were arrested—and later convicted—tensions emerged between the two agencies because a police officer showed photographs of "persons of interest" to an imam who tipped off suspects, forcing the FBI to act early. Now, numerous of NYPD detectives are being called to testify in front of a grand jury about the leaks.

The Daily News reports that four detectives have testified so far: "It was not clear exactly what leaks are at issue. Sources said one of the leaks was so serious it was included n a classified briefing for President Obama, who made his displeasure known." The Wall Street Journal adds that besides being upset about the 2009 subway terror plot, "officials at FBI headquarters and the Justice Department have been furious over leaks related to investigations, particularly during the investigations ... of attempted Times Square bomber Faisal Shahzad a year later. In both instances, senior law enforcement officials worried that leaks to the press were compromising their ability to catch suspects and collaborators in globally-hatched plots to detonate bombs on U.S. soil."

Roy Richter, President of the NYPD Captains Endowment Association, told the Post, "It’s highly unusual for a local law enforcement agency to be directed to testify before a grand jury in Washington DC.” But it's not unusual for the cops to throw its unshredded documents out into the trash.
