Even with a weapon, one against 10 in very closed quarters is an almost guaranteed end result for the victim. You may take a few out with you, but it's not gonna end well.
My money would be on avoiding this environment altogether.
I had the misfortune of visiting DC on business one summer. Not realizing how close the airport was to my hotel, I got a rental car and ended up lost like an idiot (before the GPS days). It was a real scary place to be at midnight...
You've all heard that old story about running red lights because you were afraid to stop... well that's exactly what I was doing. If you stopped at a red light, as soon as you stopped rolling, the group of thugs on the corner would start to approach your vehicle. There was a reason the area had little traffic and I knew it.
I swore to never return and I haven't. I wouldn't even drive through that place again without a tail gunner and a navigator.
When I first started FReeping with the DC chapter during Clinton, I would often drive to DC from NJ. At first, not knowing the area, I often would make a wrong turn and get lost. there is no such thing as doubling back to get back on track in DC! The physical set up of the streets had a purpose at one time, I understand, but it is daunting when you don’t understand it. So often I’d realize I was NOT where I should be, and it was scary trying to get back on track! (no GPS then)
