Probably one third of cops are dedicated to the job; one third eat too many doughnuts; and one third are people who should not be given power over others. Female detectives do not show off their cleavage. Many cops carry a drop or a throw-down. Cops plant evidence and lie on the stand. In our midst are sadists and racists who taint the rest of us. And the greatest contributor to solving crimes is not the lab but the informant, usually someone who skipped toilet training and couldn’t make a peanut butter sandwich with a diagram.
