The Chicago Police Department's use of force model allows for "direct body mechanics against body structure" as a method of control when someone's actions are "aggressively offensive without weapons or will likely cause physical injury." Other options include officers using weapons or deploying a Taser or a dog.



Officers are supposed to adjust the amount of force they use based on the amount of resistance they encounter, according to a directive explaining the model.



"As the subject offers less resistance, the member will lower the amount or type of force used," it says. "As the subject increases resistance, the member may increase the amount or type of force used."



Guglielmi said that the department wouldn't comment on how the model applied in this case.



"IPRA is doing an independent investigation into these very circumstances, and the department does not want to say something that could prejudice that," he said.



Dean Angelo Sr., president of the Fraternal Order of Police lodge that represents the officer, said the department appears to be jumping to conclusions by relieving the officer of his police powers.



"It's not how it's always been," Angelo said. "It's just a reaction to, whether it's the media or the community or politics, this seems to be the trend or the environment we're in now, with this new trend of jumping to stripping an officer before the incident's investigated.



"If that individual complies to the orders of the officer that's trying to take him into custody, it's over," he added. "It's simple compliance, and a lot of these situations that have been headlines would not be in the headlines.



"There's a segment where the officer is asking not to be bit — 'Don't bite me,' " Angelo said. "Then you turn and you grab an officer's throat. If you drop your weapon, the situation's over. It comes down to compliance."
