Gwinnett County police fired Mcdonald the next day. Robert McDonald was canned Thursday after the first video came to light involving motorist Demetrius Bryan Hollins, the Gwinnett County PD says.
"We acknowledge that the actions of these two officers have implications that will be felt for some time", a police department statement says. "The revelations uncovered in this entire investigation are shocking", read a Gwinnett PD statement tweeted Thursday night.
"What happened yesterday, at the hands of one of my former officers, was embarrassing - not only to the Gwinnett County Police Department - but to all law enforcement".
An ambulance then responded and treated the handcuffed man. Police say the officer's shift commander initiated an "immediate investigation". McDonald was subsequently placed on administrative leave and his department-issued firearm was taken.
In the incident report, the officer said he stopped the vehicle because it did not have a license plate and instead a blank piece of white cardboard where the tag should have been.
Police Chief Butch Ayers said when Bongiovanni spoke with internal affairs, he "said nothing about the punch", an action the chief called "unreasonable and unnecessary".
Police released dashcam video of the confrontation, which occurred Monday after the officer left his patrol auto and approached accused jaywalker Nandi Cain Jr. on a residential street.
"I am nearly at a loss of words about what we have had to go through today for the unwarranted actions of two of my officers", he said.
The veteran policeman then called called for back up and a response call was answered by McDonald, who preceded to kick Hollins while he was handcuffed on the ground.
From there Bongiovanni punches and tasers Hollins. His report maintained that he smelled marijuana on Hollins and that Hollins tried to resist arrest.
The report mentions McDonald arriving at that point but makes no mention of contact between McDonald and Hollins.
Hollins' lawyer, Justin Miller, said the incident would likely have been gone unreported if it had not been caught on video.
Asked what message the incident sends, Ayers said, "We have standards, we have policies, and we're going to hold ourselves to those standards and to those policies".
Public outrage at how police departments responded to previous misconduct accusations only partly explain the reason for the swift action this week in California and Georgia, according to Alexander.
The officer then realized he had arrested Hollins in August 2016 for having marijuana and a loaded gun in the vehicle.
According to jail records, Hollins faced charges relating to a number of traffic offenses such as driving without and license and small possession of marijuana but was released later on Thursday afternoon.
