Citizens on Patrol supports Colleyville

Two departmental police patrol vehicles are manned by COP volunteers, as well, who drive them throughout the community supporting patrol efforts without participating in enforcement actions, Prewitt said.

"I wish we had enough participation and vehicles to where they were out every day, 18 hours a day," Prewitt said. "Especially on weekends when business gets heavy."

COP volunteers attend departmental briefings, which coordinate where officers will be focused and where enforcement efforts are being consolidated at any given time, Prewitt said.

"They help us in ways we can't even really go into detail about," Prewitt said. "Some of the programs they are involved in we like to keep quiet—sensitive areas in crime prevention."

Colleyville held the first regional meeting of COP organizations from throughout north Texas in May, offering full-day training and information-sharing, he said.
