I had understood from earlier postings that the directions are from northern Maryland (presumably not including Montgomery County) to the Beltway. The source is apparently a Newsweek article.

If you are the sniper and you scout an area before you carry out the shooting why would you need directions. Directions are something you give or take if you are going somewhere you've NOT been before? Several shooters taking direction from a central figure. Do the police say it's the SAME gun or the same TYPE of gun?
