Tribal activists of the Strong Heart Society have conducted annual blockades since 1999, trying to intercept alcohol and drugs being brought into the reservation. For instance, in June 2006 tribal activists had protested the beer sales by blockading the road to confiscate beer bought in Whiteclay. The blockade was to be held within the reservation boundaries. The activists had lifted the blockade after agreeing to work with Chief of OST Police James Twiss on ways to limit bootlegging. According to Twiss, the roadblock was illegal; however, the police department lacked the money and manpower to do more to interdict bootlegging from Whiteclay to the reservation.
