There are a lot of ways of being "robbed" while traveling, and many are not covered by the poll. For example, I've never had anything stolen from my panniers, hard or soft, but I've had shoes stolen twice--once from atop my bike while I napped a few feet away. That was somewhere in Argentina. I had someone run a credit card twice in India and didn't discover the theft until I arrived home many months later; the money was substantial, in the thousands of dollars, but I got it back. I've encountered lots of pickpockets, none successful. I've been short-changed in a variety of ways, although never for significant amounts. Etc.

All of this rather pales in comparison to the sorts of things that have happened at home in America; knives pulled on city streets, cash stolen from my home, an incident of threats from a couple of hitchhikers I'd picked up (they backed down when I, somewhat foolishly, came right back in their faces), even a semi-famous boss who used to vanish on paydays and routinely skip out on bills.

I'm normally pretty cautious with my possessions, but often a little bit reckless with my personal safety. This has worked out just fine, for the most part. Limiting opportunities for opportunistic theft is probably the best protection; a philosophical attitude toward ephemeral possessions helps, too.
