Good video that shows a Sheriff's Deputy in New York (?) schooling a thuggish TSA official who was trying to stop people around a TSA checkpoint from filming and advocating against TSA policies. TSA knows that they can't stop people from filming a TSA checkpoint, and includes that information on its website but its officials either don't know or think that they can arbitrarily create law and regulations at a whim.
Note that this isn't a low grade TSA worker, this isn't a training issue, this is the Director of Public Relations at the regional office. I can't believe that this behavior is accidental or uninformed.
