I have my doubts about that so-called gun store.
1. That NYPD car in the establishment shot is just too coincidentally cute. A film maker can rent a phony movie-ready NYPD cop car any time.
2. Without that cop car, which is probably a movie car, nothing proves that the storefront is in New York City.
3. Did anyone hear even the slightest NYC area accent? Almost all of them have that flat-neutral Great-Lakes area-without-the special "a" sound that trained actors learn to develop--so they branch off into whatever accent they need for a part.
4. Granted lots of non NYC folk take up residence there to work, etc., but they would not be as stupid about guns as the typical NYC native would be.
5. Without all the federal, state, and city permissions, these people committed multiple felonies. The NYSRPA has asked the AG for an investigation.
