After shooting his girlfriend Saturday morning, 28-year-old Ismaaiyl Brinsley of Union City, Georgia traveled from Baltimore to New York and gunned down two NYPD officers, apparently in retaliation for recent police-related homicides. According to some commentators, however, Brinsley was only partially responsible for the murders, aided by accomplices Bill de Blasio and Barack Obama.

During a press conference held outside Woodhull Hospital, Patrolmen's Benevolent Association President Pat Lynch said, "there's blood on many hands tonight" and "that blood on the hands starts on the steps of city hall in the office of the mayor."

Former New York Governor George Pataki shared a similar statement via Twitter, calling the shocking murders "a predictable outcome" of Mayor de Blasio and Attorney General Eric Holder's "divisive anti-cop rhetoric."

On Sunday, former New York City Mayor Rudy Giuliani weighed in, telling Fox & Friends it "goes too far" to blame Mayor de Blasio and ask he resign, before clarifying that de Blasio should still be held accountable, saying:

But I don't think it goes too far to say the mayor did not properly police the protests. He allowed the protesters to take over the streets. He allowed them to hurt police officers, to commit crimes, and he didn't arrest them. And when you do that, similar to what happened in Crown Heights, you create a great riot. He should have known better. For that he has to take accountability.

Giuliani had even stronger words for President Obama, Attorney General Holder and Rev. Al Sharpton:

They have created an atmosphere of severe, strong, anti-police hatred in certain communities. For that, they should be ashamed of themselves.

Tea Party Republican and former Illinois congressman Joe Walsh went even farther, asking people to "connect the dots" between statements by Obama, de Blasio and Holder and Saturday's murders.

Appearing on CBS' Face the Nation, Republican Senator Lindsey Graham momentarily brought responsibility for the murders back to Brinsley, saying, "I blame the shooter and nobody else," before adding, "The tone [de Blasio and Holder are] setting around the rhetoric regarding the cops incites crazy people. But I blame the shooter."
