CHARLOTTE, N.C. (CBS Charlotte) – “Occupy Charlotte” protesters have nothing to occupy when they need to go to the bathroom.

A Charlotte city ordinance doesn’t allow anyone to erect semi-permanent structures, which include portable toilets.

For over two weeks, a group of approximately 25 people have camped out on the Old City Hall lawn. During the day, they can use public facilities or local businesses, but it’s more difficult to find a legal place late at night.
