Is this the beginning of the end for Occupy DC?

The District‘s health department has expressed sanitation concerns about the Occupy DC encampment saying that the trash that’s piling up is bringing around rats. After sharing their concern with DC Mayor Vincent Gray, it seems he too is considering evicting Occupiers. But WJLA reports, a lot of people who live and work near the public parks say that the rat problem is nothing new. So is Mayor Gray using the rat issue as an excuse to get rid of Occupiers?
