The U.S. in 2010 signed onto the newish international human right to clean water and sanitation, but I wonder how many of those involved in the ratification expected it to lead to consequences like these [Sacramento Press]:
An appointee to the United Nations Human Rights Council has issued a four-page memo warning Sacramento mayor Kevin Johnson that local officials could be violating the human rights of the homeless people living within the city. In the January 23rd dated letter, Catarina De Albuquerque, the Special Rapporteur on the human right to safe drinking water and sanitation for the United Nations human right council, says that the current policy of evicting the homeless from their “tent cities” and denying the homeless with safe access to clean water is, in effect, prohibited discrimination based on their economic and social status.
