A woman has been filmed spitting at a demonstrator during a protest staged by Chicago police officers who denounced Mayor Rahm Emanuel as ‘anti-police.’

The incident took place Wednesday at Chicago’s City Hall, where the Fraternal Order of Police Chicago Lodge 7 was organizing a protest against the mayor.

One of the demonstrators marching with the police union is seen getting into a heated confrontation with an unidentified woman.

As the demonstrators walk by her, she is seen yelling at one of them. She then tries to spit at him, though it doesn’t appear the saliva reached its target.

The video was posted by the Fox News Channel.

Emanuel, the Democrat and former White House aide to President Barack Obama, has been criticized by police officers in the Windy City for ‘pandering to police-hating media.’

The anger at Emanuel stems from a recent decision by an oversight agency to suspend Officer Robert Rialmo without pay over the fatal 2015 shooting of Quintonio Legrier and Bettie Jones.

Legrier, who was 19 years old at the time of his death, was carrying a baseball bat. Jones, 55, was an innocent bystander.

Chicago’s Civilian Office of Police Accountability ruled that the shooting by Rialmo was unjustified and recommended his firing from the force, according to the Chicago Tribune.

The city’s chief of police, Superintendent Eddie Johnson, disagreed with the decision.

Rialmo will not be charged with a crime.

The matter has now been referred to the Police Board, which must make a final determination.

‘This ruling has essentially undermined the use of force taught and employed by police officers,’ FOP Vice President Martin Prieb told WLS-TV.

‘Because of this ruling, no officer knows when he or she can use force, placing them and the public in danger.’

Prieb said Emanuel failed to adequately support the police.

‘Is this the kangaroo court that decides police misconduct allegations? Sadly, it is,’ Prieb said.

‘COPA is a political witch hunt on police officers. The investigations are unfair and politically motivated.’

Police officers are also unhappy because they have yet to agree to a new contract with the city.

The old one expired last July.

Emanuel said in response that he is trying to strike a balance between supporting police while also addressing the needs of the community.

‘The issue of reform can be contentious, I get that. It can be loud,’ Emanuel said.

‘But it doesn't deter us from making the necessary changes, necessary investments to achieve both the public safety and the reforms we need.

‘When you have people on either side of the police reform issue criticizing, it's a sign we're hitting it down the middle of the fairway as we continue to build trust between officers and residents, ensure oversight and accountability, and give officers the tools and training they need to be proactive in the crime fight.’
