As a playwright you'll be aware of unconscious influence. The genius mocking Leicaphile Ikanagas in one of his Leica videos on youtube (Video 9) has on the table in front of him some Leicas, some stacked $100 bills, some bullets and a gun. If you haven't seen his videos they are an absolute treat. The best is the one on the Noctilux. (When it comes to the aperture ring and f stops he prefers the even numbers....)
Actually the handgun as an incidental first appeared in Video 6, the Monochrom review.

One of the commenters to Video 9 quotes your fellow playwright, Chekov:
"If in the first act you have hung a pistol on the wall, then in the following one it should be fired. Otherwise don't put it there." Anton Chekhov
