I agree with your point...and those suburban places, no. Not what any young person is looking for. But all those NW PJs are, I think, long gone. Sursum Corda, Kelsey Gardens, a number of the dicey private complexes in the North Cap and Georgia/7th corridors are demolished and it's changed nearby neighborhoods a lot.
It's been almost 12 years since some kids pulled a gun on me near Georgia and Iowa (actually not far from that Seth Rich robbery/murder), violent crime has dropped exponentially since then. Always good for naive people to get aware of their surroundings, but DC is changing fast.
