people leave glass jars of urine on my curb. it not like the city takes any responsibility of that but that's the nature of this whole environment, it's very dysfunctional. >> here at venice beach, this is a good example of public toilets that are open to the homeless. each of these units, permanent facilities here on the beach cost the taxpayers of california hundred $74,000 per toilet per year to operate in the porta-potties, that are around town, $320,000 a year to erect and maintain. >> along venice beach, homeless some posing as artists, have overtaken the boardwalk. scattered encampments line the beach and the side streets running off of it. >> one off my neighbors just lat year was riding his bike on that bike path over there in one of these young kids who was freaked out on meth, steps often slugged him in the head, knocks him out.
