http://rt.com/usa/news/tsa-security-smith-wsmv-920/ A former TSA supervisor has been told he’s under federal investigation for blowing the whistle on security lapses at the Nashville International Airport in Tennessee. Gerald Smith, a one-time agent with the Transportation Security Administration, told Nashville’s WSMV News in October that not only had many agents in the area airport repeatedly failed security tests, but that the TSA seemed reluctant to retrain those who weren’t up to snuff. Smith spent seven years with the TSA before coming clean to WSMV when they interviewed him earlier this year to comment on documents involving the TSA’s Threat Image Projection, or TIP, program. The network obtained documents from 2009 through 2011 that showed that many TSA staffers that were tested using TIP failed to spot contraband being brought through airports in carry-on luggage. Should an agent fall below 75 percent in testing, they are required to be retrained within a month. Smith said that simply wasn’t the case in Nashville. Now just weeks later, Smith has reached out to WSMV again to talk about the TSA’s security problem, but he doesn’t have an update that will make flyers feel more safe. According to Smith, he’s now been approached by the TSA and told he’s under investigation for reporting security flaws at Nashville International. “After our investigative series aired, Smith received a letter from TSA that stated he is under investigation for disclosing information about security screenings, security training materials and identifying information on transportation security personnel,” WSMV reports.
