I saw this on the Washington Times' website the other day, pretty interesting. I take issue with calling 14th and Girard a "dangerous and deadly stretch" of the neighborhood and one of the city's "most notorious crime areas," but the Times' writers and readers probably all live in burbs.
In any case, it's an interesting idea - maybe sprucing up the neighborhood would bring more people to the park, get residents involved, and make residents think more about their neighborhood and thus reduce crime. The organizer, amusingly named Lola Bloom, said "You have the ability to take ownership and change the community. The area has a completely different feel and attitude when people take charge and change it for the better." Other residents say more kids are there, which changes the dynamic of the park.
I think it's in this area.
