Candidly, I ordinarily resent television actors trying to go beyond their roles to act as spokesmen for their on-the-air professions.

Ed Asner, of the old "Lou Grant" show, a marvelous, quite realistic portrayal of newspaperdom, had no right to appear before Congress as a putative spokesmen for those of us truly in the craft.

Consistency being, as a wise one once said, a hobgoblin of small minds, I've got to grit my teeth and voice thanks and praise for Michael Warren, who plays a policeman in NBC's "Hill Street Blues," for coming unpaid from Los Angeles to Washington on Tuesday to lend his name to a year-long, $2 million fund-raising program for the D.C. Metropolitan Police Boys and Girls Clubs. Warren, in effect, played a cop though he's not one.

He's a great young man, we found at the party that recognized his Washington activity.

The party was nice, and was attended by more than a smattering of official Washington. The crowd included Sen. Strom Thurmond (R-S.C.), chairman of the Judiciary Committee, and D.C. Police Chief Maurice T. Turner Jr.

As for the campaign, appeals will be sent to individuals and visits will be made to corporate officials.

The money is for additions and improvements to the clubs, which serve thousand of inner-city youngsters.
