In 2006 a lawsuit was filed claiming that Willis removed his gun, and placed it to the head of a then 12-year-old boy, who was riding his scooter, and failed to stop.
It also says that Willis threatened to shoot the boy, if he and his mother did not back up. Source
In 2007, Shreveport police officer Wiley Willis arrested 38-year-old Angela Garbarino on suspicion of drunken driving.
While in custody, as captured on the video below, Garbarino begins arguing with Willis about what she said is her right to make a phone call.
About a minute later, Willis walks over and turns off the video camera. When the camera comes back on, Garbarino is lying on the floor in a pool of her own blood.
She was later photographed with severe facial injuries she says were the result of Willis beating her. Willis' attorney stated that she tripped and fell while the camera was off.
After the video went viral, Willis was fired, but has never been criminally charged.
In October of 2009, the Shreveport Municipal Fire and Police Civil Service Board voted to reinstate Willis on the police force.
He'll get full back pay and benefits for the year-and-a-half he was fired.
The reason? During the internal investigation of Willis, a polygraph machine operator failed to record the results of his Q&A with Willis.
This apparently is a violation of Louisiana's "Police Officer's Bill of Rights," a set of guidelines every department must follow when investigating officer misconduct.
Garbarino won a $400,000 settlement from the city of Shreveport last year. (source)
