DENVER — This video shows the moments an off-duty Denver corporal working security loses his temper and knocks a handcuffed man unconscious.

The incident occurred last April at Jackson’s, a downtown bar, where Cpl. Oestmann was off-duty working security, reported KXXV. The retaliation by Oestmann occurred after the man spit on him.

“The guy clearly assaulted the cop, but that’s for sure excessive force. The guy’s handcuffed and not a threat to a cop,” said civil rights attorney Richard Barnwell.

Denver police released body cam and security camera video of what investigators say occurred April 14, 2018, after a fight broke out. Oestmann reportedly handcuffed Kevin Watson and kept him in a chair in the basement when things got testy.

The video shows several minutes of Watson berating and spitting at Oestmann’s feet, using vulgarities and taunting the corporal. However, Watson then spits at Oestmann’s face, and that’s when Oestman reportedly punched him and kneed him in the chest.

“You will not spit on me again! Do you understand me?” yells Oestmann. Oestmann later admits he lost control in the video: “Got a little violent there.”

As part of a plea deal, Oestman will not serve any jail time. Instead, he’ll receive a deferred sentence and will take anger management classes, according to the DA’s office.

Oestmann is on desk duty, according to DPD, while the department investigates internally. The Denver Post reported Oestmann’s guilty plea and the entire case will be wiped clean if he follows court orders for a year.

In a statement to Denver7, the district attorney’s office said Oestmann’s deferred judgment requires him to complete anger management and treatment as recommended by a third-party specializing in psychology and trauma for members of law enforcement. According to the Post, Oestmann has 10 commendations in his 14 years on the job. He also has received complaints regarding inappropriate force, but none that were sustained.
