No kidding!
I don't see where it allows for the data to be separated out, though.
For example, if I want to know how many people were killed using a gun in Illinois, I can locate that data. What I don't know about is if anyone compiles data to arrive at that number without Chicago being a part of it, or NY state without NYC. I think that would be very revealing to look at those numbers.
Blessings,

I'm curious about what exactly you mean. By that I mean what would you expect it to reveal/prove? I'll try to compile some data on the issue though, it shouldn't be too difficult!
