Tom Berger, former chairman of the PTSD committee of the Maryland-based Vietnam Veterans of America, said post-traumatic stress can easily manifest itself in criminal behavior. "It interferes with your thinking process. You have high anxiety. You do strange things like taking U-turns, or carrying loaded weapons in your car," said Berger, who has worked to change the criminal justice system for veterans. James Campbell's experience may typify that of many veterans. The 28-year-old Middletown resident now works as a veterans' employment representative for the state Department of Veterans Affairs. He said he returned home in a hyper-vigilant, ready-for-battle state of mind. Road rage and driving drunk were problems."When I got back, I felt I was indestructible, especially when I was drinking. I didn't care whether I would get into a car and drive drunk," he said. Berger said jail diversion programs should include treatment and recovery and a mentoring component. He said some Vietnam veterans incarcerated when they returned home from war remain in jail. Jim Tackett, director of veterans' services for the state Department of Mental Health and Addiction Services, said the state's jail diversion program will work closely with mental Health officials, the veterans administration and the criminal justice system to identify veterans who need help. "Some veterans who commit minor crimes that are the direct result of traumatic wartime experiences need treatment, not incarceration," Tackett said.
