I was listening to Roger Hedgecock bash Mexico again the other day. He was focusing on how dangerous it is for tourists and never once did he link the violence between the cartels there with the demand for illegal drugs here. Not only is our neighbor's house on fire ["Political Lunacy," Feb. 6], but with our insane "war" on drugs, we're pouring gasoline on the hot spots. Anne Wayman, National City [end]
