Anne Tompkins: March 26, 2014, was a shocking day for Charlotte. A city, which prided itself on a tradition of honest government and public service, learned that its newly elected mayor was not honest and had sold his public office for personal gain. Today, Patrick Cannon has admitted that he violated his duty of honest services by taking bribes. But it is a new day for Charlotte. Mr. Cannon has pled guilty and will be held accountable for his breach of trust, and he will face the consequences for his offense.
