Police Brutality Investigation

As the FBI and the U.S. Attorney's Office join the growing investigation, new information is emerging about the officer accused of brutality.
30-year-old Wiley Willis, who was fired February 5th, had two lawsuits filed against him in 2006. One by a mother who says Willis put a gun to her son's head and threatened to shoot him. Another by a woman who says she was arrested because she filed a complaint against Willis.
Most recently, Willis is seen on tape, recorded November 17th, with 42-year-old Angela Garbarino, who'd been arrested on DWI and hit and run charges. The pair appear to struggle, before Willis turns the camera off. When it comes back on, Garbarino is lying down, a pool of blood next to her.
She had a broken nose, two broken teeth and two black eyes. She says Willis beat her up. He says she fell.
Shreveport Police Chief Henry Whitehorn says he is outraged by the video, which is why he fired Willis. But still, he did not charge Willis with a crime, and he defended his department's policy of turning off cameras.
"Once officer willis determined she was not going to submit to the chemical test for intoxication, he decided to end the testing procedure which included videotaping" Whitehorn said. " Turning off the tape at this point was standard procedure."
The Shreveport Police Union, meanwhile, is coming to Willis' defense, saying the chief didn't follow protocol, and that Willis's officer's bill of rights was violated.
"We wondered why there was a firing if there is no criminal case," said Police Union President Michael Carter. "This investigation is rather unorthodox."
The union says they believe Willis' story that these frightening injuries were sustained when Garbarino fell down.
