File - In this July 28, 2010 file photo, Greg Ebert, a salesman at Guns Galore, poses for a photograph in Killeen, Texas. Ebert called the police to report a suspicious transaction with Pfc. Naser Abdo, an AWOL soldier from Fort Campbell, Ky. who later arrested with bomb making materials in Killeen, Texas. Ebert's tip led to the arrest. Tight security measures are in place at Fort Hood and neighboring city of Killeen in preparation for the start of jury selection Tuesday in the capital murder trial of Maj. Nidal Hasan, the Army psychiatrist charged in the 2009 mass shooting that left 13 dead and nearly three dozen wounded. Ebert appears in the poster under the quote "He said something; would you?"
