Three years after receiving approval from the Oklahoma City Council, the Oklahoma City Police Department rolled out their full body-worn camera program Friday.

“We're full functioning,” said Capt. Bo Mathews, spokesman for the Oklahoma City Police Department, who said the small devices are expected to have a big impact in terms of transparency, accountability and fostering better public trust with the department.

With 345 cameras available, officials said all active patrol officers will be equipped with the devices going forward. The number of devices is enough to outfit an entire shift, who would then swap cameras with other officers during shift changes.

More than 700 officers were trained this month during four-hour sessions in which they learned how and when the cameras should be used and laws concerning public disclosure of the video, said Capt. Arthur Gregory.
