Most can't afford the luxury of a tent. The event did no such thing. If students really wanted to live as homeless people, they could have slept on a bench or the ground or in a box, but not in a tent. They would not have had such easy access to a bathroom. Nor do they have a police patrol to watch out for them.
Most policemen step over homeless people.
Students who participated in this event were misled. The point was to live as a homeless person, not camp out on the Landrum center lawn. This wasn't living like a homeless person. It's good to make people aware of a problem, but helping to solve it is more important. Homelessness is a real problem in our society today.
