A growing number of cities want to tackle the problem of homelessness by outlawing what are known as "acts of daily living" — sleeping, eating and panhandling in public. In Philadelphia, a new rule is targeting not the homeless but those who feed them.

When Philadelphia Mayor Michael Nutter announced the ban on serving food in public parks last March, he said moving such services indoors was part of an effort to raise standards for the homeless.
