the "mess" in DC's parks

so I just picked up last weeks Washington Post's Sunday Outlook section which serves as an expanded weekend editorial. On the last page is a short editorial, couched by two large pictures, one dipicting "tourists" in Lafayette park in the middle of a bright sunny day, and the other "homeless" in Mcpherson Square on a dark winter night. The author of the editorial argues that DC needs to clean up it's parks. As the writer puts it,

After all, what self-respecting Washingtonians would want to subject themselves to walking through ill-managed, overgrown, dying squats of land sprinkled with a statue or two and a vagabond on every bench? It is a national disgrace taht the parks in Washington are such unbelievable messes.

so according to the author, the homeless are merely a part of an unbelievable mess. Furthermore, according to the author, the solution is a few landscape artists, and some cops to keep the homeless out. He is apparently embarrassed, not by the fact that there are homeless in "the world's most powerful nation." But that those homeless are visible in our parks. He ends the editorial with "Someone should stand up and fix our parks at once."

It is clear that he thinks only one group of people count as Washingtonians, and that everyone else doesn't even count as a human.
