From what I understand, people who have homes keep their stuff on the inside. Unless they don't want it anymore, then it either goes out with the trash, recycling, or with a note that says "Free stuff."
Or by getting rid of it, does he lose his "homeless" status and therefore, street cred? And book/movie deals?
I have nothing against the guy, and I don't live near the pile of stuff, but it's a legitimate question.
