Drivers on Highway 97 between Bend and Redmond Wednesday wondered what was happening in the old Brand Restaurant. Dozens of Central Oregon police officers took pat in a mock bank robbery Wednesday to hone their skills in the event of a worst case scenario bank robbery. The officers, including Central Oregon Emergency Response Team, or CERT, had to respond to a bank robbery with the gunman taking hostages. The specially trained unit uses these exercises to learn to diffuse the danger and save lives. They prepare and train for every type of situation, and in all kinds of weather, and refine the SWAT tactics they need to employ. The team trains twice a month in various situations; including barricaded or suicidal people or drug raids.
