there is no way that the sniper could get to the beltway on foot. it is at LEAST two miles on a busy highway, passing strip malls, gas stations and numerous traffic lights in between. Pedestrians would be extremely obvious. clearly the shooter had his vehicle in that parking lot across from HD, and where he took the shot.
