Roger Witter's good intentions landed him in jail late Tuesday.

Gresham police say Witter, 48, was in an

at 533 Northwest Division Street in Gresham when two men

. Witter witnessed the theft and, instead of waiting for police, he took off after the men, firing at their getaway car.

He told police he intended to "shoot out the tires," but it is unclear where the rounds ended up, though police said he fired in a direct line with the Gresham City Hall Max station and the adjacent Park & Ride.

Witter, a customer at the store, told police he didn't feel that his own life – or anyone else's – was in danger. He said he was trying to help police. But instead he got himself into hot water.

Officers ended up arresting Witter, accusing him of unlawful use of a weapon, reckless endangerment disorderly conduct and unlawful discharge of a firearm. His handgun and concealed weapons permit were seized.

"It is important to remember that no matter how frustrated one may be with crime and the criminal justice system, it is not permissible to use deadly force in this type of situation," Gresham Sgt. Rick Wilson said in announcing Witter's arrest. "Those two rounds could've gone anywhere. In fact, we're still not sure where they went. They could've struck an innocent bystander or damaged property."

Wednesday morning, a gun lobbyist said he realized that Witter was trying to do the right thing but didn't show good judgment.

"I understand the person's frustration," said gun lobbyist Kevin Starrett, with the Oregon Firearms Federation, a pro-firearms group. "I can understand his desire to be helpful. But it was not the thing to do. You cant shoot someone's tires out; its just not TV."

The two suspects, who fled in a silver-colored Chrysler, remained at large this morning.

Both are described as 5-foot-10 to 5-foot-11 inches tall, and about 20 to 30 years of age.

One was wearing a gray and black horizontally striped hooded sweatshirt, blue jeans and white tennis shoes. The other was wearing a brown hooded sweatshirt, blue jeans and dark shoes. Their Chrsyler was last seen heading westbound on Northwest Division.

Witter, meanwhile, has been released from jail.

Reached at his Rockwood home this morning, Witter talked to The Oregonian.

"I'm not a cowboy," he said. "I'm not a hero. I was just doing what I always try to do: help."

AT&T employees at the store Wednesday morning declined to talk about the incident, but a spokeswoman for AT&T issued a statement.

"AT&T takes this matter very seriously," said Colleen Smith, spokesperson for AT&T. "We are cooperating with law enforcement and I'd refer you to law enforcement for any further details or comment."
