In the wake of the Sept. 11 terrorist attacks, police officers and firefighters were placed on a throne and adored throughout the country.I still remember the words of McMinnville Police Chief Bryan Denton in a conversation we had a couple years ago. He said, "After 9-11, police officers could do no wrong."Clearly the pendulum has swung in the other direction and police officers have come under fire -- literally -- from the American public.By now most of us have likely heard about the high-profile case in Dallas where five officers were killed and nine others were wounded by a sniper. Since the Dallas tragedy, officers have been shot in Michigan and Georgia.
