What would you do if a stranger aggresively approches you?

About in January, I was taking night photos in the city, trying to get nice neon sign pictures, and when I was trying to find the right angle to take a certain picture of a sign this guy approches me, telling me "You better not have taken a picture of me", "I'm being fucking serious I saw you pointing your camera at", "Don't make me break your fucking camera". First of all I was shooting on a film camera, I can't just take whatever photos because that would be a waste of exposures for me, second I can't prove that I wasn't taking pictures of him because it's not digital. This interaction really pissed me off because I had my tripod set up and he could've easily broken my camera if he got aggressive.​Pretty much what would anyone have done in my scenario? (Yes, I told him to relax, that I wasn't taking a picture, just trying to maintain my cool) via /r/photography https://ift.tt/3cyobjl
