"Rails" July 22, 2010 (3rd day after eviction of homeless)

This is a video of "Rails" on the 3rd day after the eviction of the homeless. Now that there aren't any homeless living there, will the area be used for something? It seems like they're gating up the area. Was it necessary for them to evict homeless people to use this area for something else? Is it more important then homeless people not having somewhere to stay? Could they have not helped and made sure that all the homeless people had somewhere to go after the eviction? These are some of the questions that I think about every time I pass this area.
