DMs call but seems likely that if some dude calls out "Its Sherriff Bart of Rock Ridge - now throw down your weapons" and he a) sorta looks like the rumours and b) has done something reasonably awesome (or looks badass) then its a reasonable assumption that he is indeed the person of legend.
That said, I can't help thinking back to Braveheart where William Wallace was said to be 7ft tall and able to shoot balls of fire from his a*@$, so again, its DM call.
