> Someone who is panhandling wants money and they get very angry when you interrupt that process. At least in the US, the panhandlers tend not to be the genuinely homeless--they mostly tend to be scummy people. It's a semi-regular news occurrence for someone to follow a panhandler with a camera to find out they really aren't homeless.

My belief is that this is a very small percentage of beggars and the videos are so widely shared not because they reflect a common situation but because they make the people share them feel better about walking on by. I don’t actually think that you can determine that someone isn’t homeless just because they don’t want to accept food from you.
