I suspect the bigger issue with having a "5D2" strap over being mugged is when the middle-aged, semi bald man with a pot belly earned after too many years scoffing pies wanders over during a shoot and says the following:
(Pinch nose whilst saying it)
"Aww gee, I see you got yourself one of them there new 5D's! Dang!(:evil
That there's one hell of a nice camera you got there. It's got the high ISO and 21Mangapixels right? You know I take pictures too, you wanna see some of them on my portable drive I carry around for just these occasions to bore the ***t out of people!?"
It's at that point I'd be looking for the nearest mugger to spare me the pain... Go away, you cock.
