Re: I live in a neighborhood so bad...
No, it just means that it's so dangerous that you are likely to be shot by two different people at the same time. In most places, you're not likely to get shot at all. In dangerous places, you might be unlucky and get shot by one person. However, this place is apparently so dangerous that there could be two (or more) people shooting at you at the same time.
This does not sound like somewhere I would want to live!
