The plan came just in time for "The Border Security Expo & Conference" being held a few blocks away from the state capital building at the Phoenix Convention Center. Conference organizers said they expect about 1,000 officers from local, state and federal departments to attend, including sheriff's offices, U.S. Marshals, D.E.A., I.C.E., and the U.S. Border Patrol. So amidst the SB1070 controversy, deputies who could potentially enforce SB1070 were out checking out the latest assault rifles. Image: Getty/John Moore.
