According to a TV station report, prosecutors don't like him, criminal defense attorneys find that he's not a credible witness and a Phoenix jury didn't find his story believable.
He's a former seven-year veteran of the Phoenix Police Department. A jury recently heard him testify in a DUI case and then took less than 10 minutes to reject his version of events and find the defendant not guilty of all three charges against her.
According to the TV report, defense attorneys came forward to say they had dealt with the officer in the past, saying he was not a credible witness in other cases either.
The case began last May when a man was pulled over for not keeping his vehicle in his lane. His wife was in the back seat of the car.
The officer had the husband step out of the vehicle for field sobriety tests. But the wife needed to get out of the car, too, in order to use a bathroom.
She told the jury that she repeatedly told the officer she had to run across the street to use a bathroom, but that she couldn't get out of the car because the child safety locks were on.
She eventually crawled to the driver's seat to get out, but because she was in that seat, the officer arrested her for DUI.
If you use the link below to get to the original article on the officer's testimony in court, you'll read of his exchange with the woman's defense attorney; testimony another attorney described as the most disrespectful she has ever seen from an officer.
A prosecutor filed a formal complaint against the former officer in 2012, stating that he "was the most difficult officer she had ever worked with," the TV station reported.
The former police officer recently resigned after being arrested for having sex with a 17-year-old Scottsdale girl.
While sex crime allegations are certainly rare against police officers, it's less unusual to hear reports that officers fail to follow proper procedures in the course of traffic stops that lead to DUI arrests.
