A lawyer for Atlanta police officer Devin Brosnan told CNN Wednesday that his client suffered a concussion and other injuries during the altercation that led to the death of Rayshard Brooks outside a Wendy’s parking lot.

Don Samuel, the lawyer for Brosnan, told Chris Cuomo that “Devin ends up taking out his Taser and yelling at him to ‘stop fighting, stop fighting…Mr. Brooks grabbed the Taser from him and shoots … Devin gets shot with the Taser.”

Samuel said that Bronsnan fell over after being tasered and “lands on his head on the pavement and gets a concussion.” He added that Brosnan followed protocol and his actions were “exemplary.”

The information is significant and raises a number of unanswered questions about the altercation between Brooks and the Atlanta officers that is coming to light. Were the officers just defending themselves? Did the officers follow protocol?

Brooks initially cooperated with a field sobriety test and appeared to be cooperative with the officers overall.  But everything changed when the officers prepared to handcuff him. It was then that Brooks grabbed one officer’s Taser and a chase ensued.

The Atlanta prosecutors allege former officer Garrett Rolfe then shot Brooks in the back, said “I got him.” The prosecutors also allege Brosnan stood on Brooks’s arm after he had been shot. Prosecutors are pushing for a felony murder charge against him. That charge carries life in prison without parole or the death penalty.

However, that sequence of events has been called into question because another video appears to show that Brook’s turned, aimed and shot the taser at the officers before he was shot.

After prosecutors brought charges against Rolfe and the other officers, a large number of Atlanta Police Department officers called in sick, while others just walked off the job.

According to local news reports the “Atlanta police patrol six zones covering some 500,000 residents. They also patrol Atlanta’s Hartsfield-Jackson International Airport.”

Later the Atlanta Police Department tweeted that “earlier suggestions that multiple officers from each zone had walked off the job were inaccurate. The department is experiencing higher than usual number of call outs with the incoming shift.” The department noted that it had enough officers to cover the zones they patrolled.
