Dear fan fiction author:
There is no "driving down to Baltimore" from Washington, DC. Baltimore is NORTH EAST of Washington. And elevation-wise, there’s no difference, so no "down" in that sense either.
Please look at a map. Except, wait, you obviously did for other bits of your fic, which makes this blunder (used twice) even more peculiar.
Dear other FF author:
Having a character be shocked and complain about an attempted robbery "within a five mile radius of the White House" — dude, seriously, do you know how big a five mile radius is? No crime in that area? Good luck. Having an otherwise security-conscious character say that is just naive bordering on ridiculous.
