Editor,After reading Professor Wadman's March 20 guest commentary, "The Triumph of evil," I have to make some comments.Mr. Wadman's 30 years of law enforcement is commendable and is his best asset in making his judgment call regarding a weapons ban. His being shot and having to deliver sad news of a person's death is not a qualification. It only raises emotion in the reader. After 24 years, and still counting, in law enforcement, I must be just about equally qualified as Mr. Wadman when it comes to experience, albeit, I've never been a chief.
