Garry Trudeau's comic strip "Doonesbury," which is seen elsewhere on this page, has brought more controversy than usual in taking on entertainer Frank Sinatra, linking the singer to alleged crime figures with Italian surnames. The National Italian American Foundation, headquartered here, sent a telegram yesterday to Trudeau's Universal Press Syndicate charging the comic strip was "the worst kind of ethnic stereotyping imaginable . . . We strongly resent singling out Italian Americans as the only bad guys."

To correct the erroneous impression today's strip gives, Aniello Dellacroce was acquitted of the 1974 murder of Charles Calise. Dellacroce was indicted earlier this year on racketeering charges. Commenting on Trudeau's strips through his spokesman Lee Solters, Sinatra said yesterday: "Garry Trudeau makes his living by his attempts at humor without regard to fairness or decency. I don't know if he has ever made any effort on behalf of others or has done anything to help the less fortunate in this country or elsewhere. I am happy to have the president and the people of the United States judge us by our respective track records."
