easy enough to tell the difference between "professional" homeless and hipster protesters.
I lived among the protester types for about ten/15 yrs in NYC - the guys descending on OWS for the free food ( and sex )are most likely recently freed convicts and residents of homeless shelters. Mostly institutionalized black & Hispanic men in their thirties & older, once the word got out you can bet that the young white hipsters were overwhelmed with institutionalized shelter residents.
The hipsters are almost all white young folks who never set foot or spent the night in the dehumanizing homeless shelters of NYC and are all urban hipsters who can quote Comedy Centrals latest liberal comedian, are decently well read & educated and wear their political correctness on their sleeve.
The institutionalized shelter residents on the other hand are frighteningly stupid, politically incorrect, don't know John Stewart from Glenn Beck, cant discuss the difference between Anarchy & Communism, do not know the difference between brown rice & white rice & have zero knowledge of hipster values/culture/language ... they stand out like a sore thumb.
Yet the hipster protestors are dimly aware that if they make to much noise about these interlopers then their hypocrisy and elitism will be on display for public consumption ...
The irony... it is a deliciously thick sauce...Indeed!! 
It gets mighty cold in NYC sometimes, I remember one winter in 85 I think, if you included wind chill factor it got to 65 below zero during the day in Central Park. I went to the park that day just to see it, yup! Still had one hardcore homeless guy in his cardboard refrigerator box/home.
