"Assassination." That's the word the 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 city 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 today, new surveillance video 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 white styrofoam box Saturday afternoon. Police say the box in his arms probably 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.

(CNN) - President Barack Obama took eight questions during his Friday press conference — and all of them from women journalists.
It was an unusual and deliberate move, considering the White House press corps has been historically dominated by men. Indeed, the first woman to cover the president, United Press International journalist Helen Thomas, didn't join their ranks until 1960.
White House Press Secretary Josh Earnest explained that the White house realized it had an opportunity to highlight the number of women who cover the White House as it compiled the list of reporters for Obama to call on.
"The fact is, there are many women from a variety of news organizations who day-in and day-out do the hard work of covering the President of the United States," Earnest said.
