I agree it's not for everyone. But especially in this city, and where some interesting urban photography exists - I think for Jules to have immediately assumed I was out looking for trouble was inappropriate.
I also put 4 gallons of water in my trunk when I drive through the desert - and kept a first aid kit/ flashlight / foodbar always on my when I lived in Manhattan. It's not a desire to look for trouble, anymore than I look to dehydrate, or get stuck on a train for 2 hrs - it's just being prepared at the cost of carrying a few ounces.
It's not like I walk around with pepper spray in one hand and a cam in the other, nobody would ever see it - just to be clear.
Bear in mind bad elements seldom confine themselves to bad areas. There have been plenty of **** murders in scottsdale - like my friend who was stabbed repeatedly and thrown in a canal, on a bicycle ride. One wonders pepper spray could have helped her - maybe, maybe not. Oh and for those who think I'm just positioning - I wish I was.
