There was a time when Don Cannon was one of the most popular television personalities in Pittsburgh. The longtime news anchor, whose tenure here was marked by troubles with alcohol, is in hot water again. Cannon was a longtime newsman at WTAE before an embarrassing onscreen meltdown in the mid-90s ended his career there. He relocated to Philadelphia but returned to Pittsburgh a few years later to work as an anchor and reporter at KDKA before losing that job a couple of years ago following a pair of drunken-driving arrests in the South Hills. Cannon subsequently relocated to California, where he was supposed to serve his house arrest and probation sentences for convictions on the two Western Pennsylvania DUI charges. But Allegheny County authorities say he failed to do so, and Cannon was picked up Tuesday by police in the San Diego area. He also reportedly faces a new DUI charge in California. I understand that some people have problems with alcohol that they can’t control, but those people are well aware of their problems, and some of them still make a conscious decision to drink and get behind the wheel of a car. In Cannon’s case, he did it multiple times. I can sympathize with a person who makes a one-time mistake, gets pulled over and blows a .08. And I give young people a little bit of slack, because I remember (barely) being a young and irresponsible kid, myself. I don't mean that young people should not be held responsible if they violate the law, but I have some understanding of their actions. However, I don't understand it when a 69-year-old man doesn't have the good sense to drink at home.
