A prosecutor said Tuesday that two Georgia men plotted to make a poison to use against government officials and federal buildings, while defense attorneys said the pair were simply talking big and committed no crimes. The lawyers’ claims came during opening statements in the trial of Samuel Crump and Ray Adams before U.S. District Judge Richard Story in Gainesville. Crump, 70, and Adams, 57, were among four men arrested in November 2011 after an undercover informant made recordings at their meetings at homes, during car rides and at a Waffle House restaurant.
