I am confused by this. Are you talking about being attacked as in being mugged or something? As in biking/walking being unsafe because of crime? Or do people in your hometown attack bikers and pedestrians because they're biking/walking? If it's the second one I'd be interested to hear more about it because that's fascinating.

Pure random attacks, completely unprovoked, to take your bike. Me being a white didn't help either as usually such events included a lot of racial hate towards whites.
