Would there be a bigger picture, showing us, how these behaviour comes into being? How it could be addressed or prevented in other ways?

It's you or them?

In the light of the recent complaints on this blog about homeless people in SF: maybe there is a completely surprising "disruption" lurking, if you do not address this subject with a "we" mindset.
