A gun could be in practically any car on the planet. Given their size, they can also be on any clothed person, and perhaps even on some unclothed ones.

Again, if that's the only criteria required to point a gun at someone, then you can point a gun at practically any person at any time they are in public. You're giving my criteria that is so broad it would be difficult to find someone or something on the planet (and perhaps off of it) that does not fit the description. You might as well ask me if a person could theoretically emit a sound.
