ALTHOUGH I don't know much about comic books, I have seen a lot of movies and watched a great de3l of television and I have failed to see anything that would make a mass of bloodthirsty killers out of the youth of this nation. And I have yet to read a television or movie critic who has.It may be that juvenile delinquency is worse today than ever before and that the problem should be pursued and solved before Armageddon. But it mi^ht be wise to direct the hue and cry at more basic causes than television and comic books. They have about as much effect on juvenile delinquency as does a parental admonition.
