A retired, disabled U.S. Marine was in his uniform with several medals when agents at Sacramento International Airport in California stopped him for wearing "too much metal." Cpl. Nathan Kemnitz was on a trip to the state Capitol building to be honored for his military service. The agents asked the veteran to raise his arm as part of standard procedure, but he could not as it was injured. "As always, all passengers with disabilities and medical conditions are eligible for screening procedures sensitive to their particular disability, medical condition or other unique medical circumstance," the TSA said in a statement.
