Black gang alliance in plot to kill cops discovered in drug and gun ring takedown

A massive gang takedown in Queens uncovered a rare alliance between the black gangs known as Bloods and Crips and a ruthless plot to assassinate police officers. The revelations came as law enforcement unveiled the chilling results of long-running Operation Under Siege - 104 suspects, dozens of guns, two slayings and piles of drugs and cash. The sprawling case was built on wiretaps - including recordings of gang associate Keith Livingston, who blabbed about plans to protect his drug turf by killing cops on patrol.
