Movies and TV have a strange relationship with guns. On the one hand you regularly have some actor coming out and declaring him or herself anti-gun. This is to be expected from people who are mostly liberal democrats. On the other hand you have lots and lots of guns in movies. Guns add drama, conflict and even humour. Frankly, without guns in movies and TV, there would be far fewer movies and TV series made, and what would be available to watch would be pretty boring.
