We are hearing for the first time from the two fired Chattanooga police officers at the center of a high profile beating case.

Sean Emmer and Adam Cooley were fired last year for using excessive force against inmate Adam Tatum. Now the duo is battling for their badges back. Last month, a federal investigation, revealed there was no "prosecutable offense" against the two men.

The attorneys representing Emmer and Cooley, along with city attorneys, painstakingly went through the video surveillance taken from the Salvation Army halfway house in Thursday's hearing.

Sean Emmer took the stand and when questioned by his attorneys; he says he had 'tunnel vision' and 'auditory exclusion' while beating Tatum with his baton. He says he did not quite remember what was going on. But Emmer also says hitting Tatum on the legs was within department policy and what he was doing what he was trained to do. Despite pleas from Tatum saying his legs were broken, Emmer did not think he was telling the truth. He says, bottom line, Tatum resisted arrest the entire time.

When a city attorney cross examined Emmer, he pointed out the fact there were plenty of opportunities for Tatum to be taken into custody. One of them was after Tatum was tased for a second time.

"You're trained in the academy that when a taser is applied, you should affect the arrest immediately there after, correct?" asked the assistant city attorney.

"That's correct," said Emmer.

"When this tase is applied, you all stand back?"

"That's correct." said Emmer.

"(In the video) Mr. Tatum, he hasn't moved."

"That's correct," said Emmer.

"The policemen are coming in, right?"

"That's correct."

"And nobody's going to affect the arrest?"

"I can't answer for them," said Emmer.

"You're not going to affect the arrest?"

"No I'm not," said Emmer.

"You're not directing anybody, 'Hey, let's go grab this guy?"

"No I didn't," said Emmer.

"You're directing people to go to the door?"

"That's correct," said Emmer.

The city also pointed out contradictory testimony from Emmer, saying in his original report made after the fight, he said he did not know Tatum had a knife on him until after the fact, but that is not what he testified in Thursday's hearing.

The city also says just because Emmer was cleared by the Department of Justice for any criminal wrongdoing, does not mean he still did not violate CPD policy on using excessive force.

Testimony was also heard from Adam Cooley, who responded as back up to Emmer. Wednesday, Chief Dodd said he took issue with Cooley punching Tatum multiple times in the face, but Cooley maintains he was using department tactics.

"You punched him a series of times?" asked Jonathan Guthrie, Cooley's attorney.

"I did," says Cooley. "During that series of punches I attempted an arm bar take down three separate times. three separate times I attempt an armed bar take down. It may look like I'm straddling him, but you can see clearly...you can see clearly that he's starting to roll over."

"Now, there were some allegations that when you punched him, his head was on the floor. Can you see in this video where his head is?" asks Guthrie.

"You can not see where the head and I believe Chief Dodd admitted earlier that you can't see where his head is," said Cooley."

The city and the defense were at odds as to whether he knew if punches to the face were considered deadly force and against CPD policy.

The defense asked, "Did you ever receive training that punches to the face were prohibited by the Chattanooga Police department use of force policy?"

"No not that I recall, and not only were they not banned, but they're also a common practice. I've seen them happen many a time on the streets," Cooley said.

But the city pulled out a test Cooley took at the police academy where he answered every question correctly. He answered yes to a question that asked if a strike to the head could be deadly force. Cooley replied he's also been taught that sometimes you need that type of force, but you have to justify why.

Cooley also argued that he never had the chance to explain the video to Chief Dodd before he was fired.

The hearing is set to continue on July 3rd. Count on Channel 3 for complete coverage.
