"Assassination." That's the word U.S. Attorney General Eric Holder used Monday night when he called the murders of two New York City police officers on Saturday.
New York and police departments nationwide are on high alert for copycat attacks in the wake of the brutal execution. The NYPD is investigating at least 15 online threats. The NYPD released new surveillance video today that captures the shooter, Ismaaiyl Brinsley, just before he went on his murderous rampage. The video shows the 28-year-old in a New York mall, carrying what appears to be a white styrofoam box Saturday afternoon. Police say the box ilprobably holds the gun he used to kill officers Wenjian Liu and Rafael Ramos.
Investigators also discovered video on Brinsley's cellphone of a New York City protest earlier this month. They say Brinsley was a spectator on a day of nationwide protests over the deaths of Eric Garner and Michael Brown.
Authorities are still trying to determine Brinsley's motivation as well as what he did during the crucial two-and-a-half hours before the shooting.
