While I know my current neighborhood is hardly the safest place in the world, the majority of the violence I have witnessed here involved black teenagers and young adults fighting with each other. As a white woman who is friendly but largely uninvolved in my neighbors' worlds, the worst I ever received was some benign drunken harrassment and a few young boys hitting on me. Almost all of my interactions with my neighbors here have been positive, even when I was digging into things some people would rather not talk about.
Seeing articles like this makes me wonder if the same thing will work in my new neighborhood.
I've already spent some time in Southwest. While the street I'm going to live on seems sleepy and quiet, plenty of people (including teenagers) hang out on the stoops just a few blocks over. There is also a very obvious income gap between my section of the neighborhood and theirs. On the one side, multi-story, expensive-looking rowhouses sheltered by tall, old trees and fronted by carefully maintained gardens line the streets. On the other, short, small, identical homes squat along treeless streets with waist-height chain-link fences and clothes lines in the back. My section of the neighborhood is mixed race; the other section seems to be almost all black.
The split in the neighborhood lies along 3rd Street SW, next to the commercial area that includes Safeway, the Metro, the CVS and Bank of America trailers, and the dirt pit that will become the new Waterside Mall. As the NBC article mentions, plenty of teenagers hang out in front of the stores there. I've said hello to them and laughed at their jokes, but I've never questioned them or challenged their right to be there as the police officer did.
When I move to Southwest I plan to start reporting on the area. This means, at a minimum, I will be walking around and talking to everyone I meet, getting to know who lives there, who works there, who hangs out, and what their stories are. Including the teenagers. Inevitably some people will disagree with the articles that come out of these conversations.
Years ago in Texas several of my guy friends realized that they could not stop me from going into places they saw as dangerous. Long before I took a Sociology class or wrote an article, I walked into places others labeled "The Barrio" or "that crack house" just to talk to the people who lived there. My friends' reaction, in typical Texas fashion, was to give me easily concealed weapons and teach me how to seriously injure or kill someone.

I never had to use these weapons, and I stopped carrying them when I started needing to pass metal detectors to get into the libraries in DC. I also stopped carrying them because I don't want to wind up accidentally killing or crippling someone over a misunderstanding or pretty theft. To me, losing my wallet is not worth someone else's life.
On the other hand, I don't want to end up with my hands held behind my back by one teenager as another one beats me up just for walking down the street. Being able to throw the person holding me would be great in this instance, but would having a weapon like a knife, a night stick, pepper spray, or even a gun help? I don't know.
What do you think? Should I start bearing arms and really practicing martial arts again, or are my best defenses being aware, making friends, and talking my way through the situations I find myself in? Do I realistically need to worry about this more in Southwest than in Columbia Heights?
