Every time a police officer uses that siren, taxpayers are footing the bill. A handful of customers are racking up some big charges.

"Literally 10% of the people in the population commit anywhere from 80-90% of the crime," said Officer David Lund of the Bryan Police Department.

They're repeat offenders who can't seem to stay out of jail. Repeat offenders, like Alton Kyle Walton II. He's been arrested 21 times since 2001, and he's only 25.

Walton is among a select group of people, Bryan Police know all too well.

"I know them well enough on sight to know what their name is, what their birthday is, where they live," said Lund.

When it comes to Walton, the Bryan Police Department isn't the only agency that's dealt with him. College Station Police have picked him up, so have Texas A&M University Police.

Brazos County Sheriff's Deputies have arrested him, even Burleson County has been in on the action. None of these encounters are free. In fact, taxpayers have picked up Walton's tab before.

Walton made 21 separate stops at the Brazos County Jail in the last eight years. Though not consecutively, he called the county jail home for 337 days.

His overnights cost you almost $13,000, and we're just getting started. Before Walton ever gets to the courtroom, the men and women in Blue have spent plenty of time dealing with him in the field, and mostly in paperwork.

Police say a simple traffic warrant arrest can take an hour, but some of Walton's more lengthy arrests took several hours and several officers.

"Eating up the tax payers monies with all of our efforts," said Lund.

If we say the average arrest time was two hours, for even one officer, those 21 arrests add up. That's almost two solid days devoted entirely to Walton.

"All that costs a significant amount of money," said Lund.

He's not kidding; the average pay of a Bryan Police officer is $24 an hour. If you multiply that times the hours spent on the Walton arrests, an additional $1000 of tax payer money went to keeping tabs on Walton.

"And thats just on the front end," said Lund. "Thats not including all the time the detectives are going to spend following up on the case, the District Attorney's investigators following up on the case, preparing the case, and then going to trial."

"Thats county money that could be going to much better causes and other things," said J.J. Ramirez, of Save Our Streets Ministries.

Walton isn't the only one overstaying his welcome. Police say there are over 100 more like him, just in Bryan. Its a reality that officers across the Brazos Valley know all too well.

"There are a lot of folks that seem to be committing crimes over and over again," said Officer Michael Kneese with the Bryan Police Department.
