<p><br /> A man has told US airport security officals that he would "get them arrested" if they touched his "junk" when conducting new security procedures.<br /> </p><p><br /> John Tyner from California could face a fine of up to $10,000 after refusing to be 'patted-down' in the groin region.<br /> </p><p><br /> He recorded his confrontation with security staff on his mobile phone which he later posted to his blog.<br /> </p><p><br /> The head of the US Transportation Security Agency (TSA) acknowledged that new controversial airport scanning and pat-down procedures are "more invasive," but said they were necessary to prevent would-be attackers.<br /> </p><p><br /> New full-body scanning machines installed at US airports create detailed images of passengers bodies that TSA agents check to see if passengers are attempting to carry any contraband.<br /> </p><p><br /> Travellers can opt out of the scanning process and choose to be patted-down by security agents, but some have complained new procedures for the pat-downs are resulting in a very physical, and uncomfortable, interaction between security agents and passengers.<br /> </p><p><br /> TSA Administrator John Pistole said at a Senate hearing that the new procedures are necessary for security.<br /> </p><p><br /> "It is clearly more invasive. The purpose of that is to obviously detect those type of devices we had not seen before, for example, last Christmas. I am very sensitive to, and concerned about, people's privacy concerns and I want to work through that as best we can. The bottom line is: we need to provide for the best possible security," Pistole said.<br /> </p><p><br /> Pistole said that there are no plans to change the current procedures.<br /> </p>
