Most of the weapons in Right Sector’s possession are believed to have been stolen from an Interior Ministry depot in the final, chaotic days of the revolution last month. A government-imposed deadline for the return of those arms passed last Friday, yet there is no way of knowing how many of them remain in private hands. Speaking about his followers last week, Right Sectors leader Dmitry Yarosh slyly told the New York Times that, “in part they handed in these weapons, in part they keep them.” The group’s menacing tone and refusal to respect the new government’s authority posits a worst case scenario that the country’s security could deteriorate along lines seen in other, post-revolutionary situations, when power vacuums let militias wreak havoc.
