Update, Dec. 20 at 10:30 p.m.: “They were, quite simply, assassinated—targeted for their uniform,” Police Commissioner William Bratton said at a news conference Saturday night. Bratton “looked pale and shaken” as he spoke to the press regarding the killings of Officers Rafael Ramos and Wenjian Liu earlier in the day, reports the Associated Press.

The two officers were not targeted for any particular reason except that the gunman had a desire to kill police officers. The two were in the area for an anti-terrorism drill, according to the New York Daily News. “The perp came out of the houses, walked up behind the car and lit them up,” a police official tells the Daily News.

“Every New Yorker should feel they were attacked, that our entire city was attacked, by this heinous individual,” said Mayor Bill de Blasio. Despite his show of support, cops turned their back on the mayor as he entered the Brooklyn hospital where the two officers died. It was a striking demonstration of how they remain angry at his support for those who have been protesting against the decision not to indict any police officers in the death of Eric Garner. The move comes shortly after the largest police union circulated a letter in which officers could request the mayor not attend their funerals, notes the New York Times.

Rev. Al Sharpton, who has organized many of the protests against police violence in recent weeks, condemned the killings. “Any use of the names of Eric Garner and Michael Brown in connection with any violence or killing of police is reprehensible and against the pursuit of justice in both cases,” he said.

I am outraged at the killing of 2 police officers in Brooklyn. That is why we stress non violence as the only way to fight for justice. — Reverend Al Sharpton (@TheRevAl) December 20, 2014

Original post: Two police officers were shot and killed Saturday afternoon when they were sitting in their patrol car in Brooklyn’s Bedford-Stuyvesant neighborhood. The gunman apparently came up to the car and shot them both without warning before fleeing into a subway station, where he proceeded to shoot himself in the head. The New York Daily News identifies the gunman as Ismaaiyl Brinsley. Both the News and the New York Post claim the gunman shot the police officers hours after he shot his girlfriend in Baltimore. Brinsley’s 29-year-old girlfriend was shot in the stomach, underwent surgery, and is expected to survive, one of her family members told the Daily News.*

The gunman appears to have traveled to New York specifically to kill police officers as he allegedly wrote Instagram posts in which he expressed a desire for revenge for the killings of Eric Garner and Michael Brown. “I’m putting wings on pigs today,” he wrote, according to the screen capture of the Instagram post. “They take one of ours … let’s take 2 of theirs #shootthepolice #RIPErivGardner (sic) #RipMikeBrown This may be my final post.” He then signed off: “I’m putting pigs in a blanket.” Witnesses say the gunman did not appear to hesitate, shooting several rounds into the car. “The perp came out of the houses, walked up behind the car and lit them up,” a police official said. Another witness told the Daily News: “He just walked up and shot that cop in the head.”
