ANDERSON, S.C. -- A local police officer claimed Thursday that he was fired for giving a speeding ticket to a popular college football coach -- fighting words in a state that takes its sports rivalries very seriously.

Officer Michael McClatchy issued a ticket to Clemson coach Dabo Swinney on Sept. 3 after he clocked him going 63 mph in a 35 mph zone in the city of Pickens, located in the same county and just 20 miles down the road from Clemson.

Word of the stop traveled fast as fans who recognized the coach and stopped to get his autograph shared the news on message boards and Internet sites. Their versions of the incident varied widely, with some saying Swinney had a meltdown and others alleging that McClatchy -- a fan of Clemson's bitter rival, the University of South Carolina -- had let his rooting interest cloud his judgment.

The city of Pickens said it fired the officer because he posted his version of events on a South Carolina message board while still on duty and using a police department computer.

McClatchy doesn't see it that way. He said he only briefly edited the post at work and is convinced that officials were just looking for a reason to get rid of him because he didn't let one of the most popular figures in the area get away with breaking the law.

"I was wrongfully terminated for doing my job. The computer issue is a red herring," McClatchy said, reading a statement while accompanied by his lawyer, University of South Carolina trustee and former football player Chuck Allen.

Swinney was late for his radio show at a grocery store when he was stopped for speeding. After McClatchy turned on his blue lights, the coach drove a short distance farther then turned into the store's parking lot, according to police video footage.

Swinney got out of his pickup truck and told the officer who he was and where he was going. The officer asked Swinney and his brother to sit in the truck while he wrote the ticket, but Swinney stayed outside. Soon fans started approaching the coach, and he even signed some autographs.

Swinney said little during the stop, but his brother can be heard on the tape calling McClatchy a "disgrace to the badge" and saying he would "get it one day."

According to McClatchy, the grocery store manager came outside and told him the mayor of Pickens was on the phone and wanted to talk to him. The officer refused to take the call. McClatchy also said police chief Rodney Gregory told him that Swinney had called him at home to complain that the officer had acted unprofessionally.
