Parisian homeless sound similar to aggressive street vendors I've experienced in SEA, they were annoying and would occasionally leave me feeling somewhat violated but never really scared, except for possible pickpocketing. With homeless here (at least in Portland and Seattle) it really depends. Most completely ignore you, some ask for money, some will be very loud and aggressive at no one in particular possibly from hallucinations or just being upset in general. A small but significant percentage will act extremely unhinged, so much so they make me nervous as a larger guy with military experience. I've heard that a lot of this is due to a new kind of meth on the streets that causes terrible psychosis.
