Public outrage continues to grow since an airport traveler posted a cell-phone video detailing what happened after he refused to walk through a full-body scanner. That passenger, John Tyner, told TSA agents not to “touch his junk.”There are currently 300 full-body scanners in use at airports across the country. The TSA plans to 500 installed by the end of the year.
