It's disheartening to read Tad Clarke's editorial on predictive dialing ("Predictive Dialing's Dead Air? A Marketer's Problem," DM News Feb. 21) in which he states: "Why some states want to prohibit the use of predictive dialers entirely is beyond me." I guess there's nothing like the sport of taking people away from assorted daily activities to answer a nonexistent phone call. Just like the telemarketing company that hangs up if anybody answers the phone, since its only purpose is to leave a message on an answering machine. Is this what Don Ameche invented the telephone for? Mr. Clarke, as editor of a major direct marketing industry publication, should represent the best of industry practices, not the worst.
