Is Mark Harmon the Perfect Pole for That?

My father was recently retelling a story over dinner that I've heard since early childhood. When he was in grade school he was playing American football. With some friends before being aggressively tackled to the ground by a boy a few years older than he black out instantly waking up in the hospital. The boy did not apologize this time in telling the story, However my father casually revealed that the tackler was Mark Harmon. Do I have a legitimate case against Mark Harmon for tackling my dad? And if so what should I say slash do upon him seeing him in quarter otherwise please advise?"
