Lawyers for Hinckley plan insanity defense

The case against President Reagan's accused assailant, John W. Hinckley Jr., will likely become a battle among psychiatrists over the collee dropout's mental state when the shots were fired.

Attorneys for Mr. Hinckley said they are willing to concede that the evidence shows he shot Mr. reagan and three others March 30, but maintained their client was insane at the time and should be held criminally responsible.The offer of a concession of fact in the case marked the first time Hinckley's lawyers had disclosed their intention of using a defense of insanity at his trial.
