Shortly after a Michigan Avenue press conference on that date was broken up by the police and one of its speakers arrested (chicago.indymedia.org/newswire/display/76587/index.php), Lyttle and fellow anti-war activist Pat Vogel were separately arrested – Brad for having the chutzpah of holding an anti-war placard while standing on a Michigan Avenue sidewalk. In December trial Lyttle was found innocent of disorderly conduct in a directed verdict. In laymen's terms, the judge decided that the prosecution had failed to meet its burden of proof even before Lyttle's attorneys, National Lawyers Guild members Charles Nissim-Sabat and Jeff Frank, had even called a single witness. Pat Vogel was also found innocent in a separate trial, defended by Guild member Melinda Power. Joining Nissim-Sabat and Frank in Lyttle's suit will be fellow Guild attorneys Jon Loevy and Kurt Feuer.

Before the Vietnam War, Lyttle was a co-organizer on various anti-war projects with legendary pacifist activist A. J. Muste. Recognizing his experience in organizing, he was tapped to work with Fred Halsted of the Socialist Workers Party as the co-organizer of logistics for the huge 1970 Washington, DC march against the Vietnam War.
