The former New York City Police commissioner blames the NYC mayor for "anti-police" anger and protests Sunday. 

Ray Kelly accused Mayor Bill de Blasio of fueling the "anti-police" anger during protests over the deaths of two unarmed black men at the hands of white police officers, Yahoo! News reported.

"I think when the mayor made statements about that he had to train his son - who is biracial - to be careful when he's dealing with the police, I think that set off this latest firestorm," Kelly said in an interview with ABC.

Kelly went as far as to say the mayor held an anti-police campaign in 2013 when he ran for mayor. 

Kelly served as police commissioner between 2002 and 2013, according to The Huffington Post. He has defended NYC's stop and frisk policy that de Blasio said he would reform during his mayoral campaign.

Kelly does not stand alone in opposition to the mayor's objections against the stop and frisk policy and his comments about training his biracial son to be wary of police.

Former New York Gov. George Pataki (R.) said in a tweet Saturday that he was "sickened by these barbaric acts, which are a predictable outcome of divisive anti-cop rhetoric of #ericholder & mayordeblasio. #NYPD."

Even former NYC Mayor Rudy Giuliani criticized de Blasio about how he handled the protests following the deaths of Michael Brown and Eric Garner.

Giuliani blamed the murder of two NYPD officers Saturday on anti-police propaganda that began four months ago with President Barack Obama, The Huffington Post reported.
