The Borderstan blog alerts us to what appears to be a string of armed robberies in the past week in their Logan/Dupont/Shaw overlap area. Three different gun-involved muggings have happened along R Street NW between New Hampshire and 13th, and another happened the other night at 11th Street NW and Vermont Ave. We also heard about at least one other armed robbery Thursday night, right around 14th and T Streets NW. Stay alert in the ‘Stan this weekend, DCist readers.
