Phoenix's Homeless Encampment Clearing Raises Concerns for Vulnerable Residents.

Phoenix officials will begin clearing one of the nation’s largest homeless encampments this week in a downtown area known as the Zone, where neighbors and business owners have filed a lawsuit calling the tent community “a great humanitarian crisis” because of open drug use, violence and property damage. The effort comes after a preliminary injunction in late March ordered Phoenix to clean up the area. City officials said they plan to remove tents, block by block, starting on Wednesday.
