Then Officer Adam Wittmayer hits Keller in the head.

"Mother *******, God.  . . . .One in custody. ******* Moron ***** You're a stupid mother ******, you know that? Stupid mother ******," said Wittmayer.

After Wittmayer and the deputy finish searching Keller, they pick him up and head towards the deputy's car.

That is when you can see Wittmayer forcefully shoves Keller into the backseat.

"We still don't condone this type of behavior under any circumstances. This behavior is wrong. So we took appropriate action, but I do not feel it warranted termination," said Waterloo Police Chief Dan Trelka.

The Iowa State General Attorney's Officer agreed. The office reviewed the incident and decided not to charge Wittmayer because of Keller's actions leading up to the arrest.

"When they looked at the totality of the circumstances. . . The suspect nearly hit a school bus. Right after that, Officer Wittmayer was laying down the spike strips and the suspect swerved towards Wittmayer," said Trelka.

 Chief Trelka said Wittmayer is a veteran of the department and this is his first incident like this.

 Chief Trelka also said Wittmayer immediately regretted letting his emotions get the best of him.

 The chief working to change officer training to prevent incidents like this in the future.
