/sigh This adds too many complexities to the story or possible stories.
If someone like Bruce Lee, Bruce Li, Chuck Norris, Jacki Chan, Arnold Schwartznegger, Lou Ferrigno, Jesse Venturi, George "The Animal" Steele, etc... began aggressively pushing me I might want to draw my gun and begin backing away. Just because you're collecting rent at the time, doesn't give someone the right to assault you.
Now, the key to my drawing is.... Agressive. I'd back away first. Use of lethal force, or even the drawing of it against an unarmed man, should be a last resort.
