You can almost sort of but not really understand the actions of Metro Transit Police Captain Leslie Campbell, who the Post reports is under investigation for failing to report a minor collision he had with a pedestrian outside the Anacostia Metro station last month. Campbell wasn’t going very fast and more or less tapped a pedestrian with his car — the pedestrian wasn’t injured and the car was not damaged. When the pedestrian declined medical treatment and walked away, Campbell made the bonehead move of not reporting the incident to his superiors. Now, if this had been not a police officer, just a minor incident between 2 individuals, it’s doubtful anyone would have reported it to the police, either. But a uniformed captain struck a pedestrian with his car, and even though no one was hurt, that Campbell decided not to immediately report the accident shows a pretty serious lapse in judgment.
