GOP US Senate candidate Juston Preble is blasting the Transportation Security Agency for inhibiting tourism and economic growth in Nevada,  due to the incompetence of their airport screening process. He says private contractors performing the same function as the TSA at San Francisco International Airport clocked an average 15 minute wait time.  Preble says “Nevada has a higher percentage of visitors who are tourists than any other state.  One out of every 12 dollars spent in Nevada is on tourism, and the inefficient and incompetent TSA is costing us profits now and jobs in the future.”   Preble also blasted the agency on a 95% failure rate for detecting hidden or disguised explosives and firearms, during testing procedures by undercover TSA quality control personnel.
