PROTECT PEOPLE FROM WHAT? He was not a threat! He was carefully searched! The TSA cleared him to fly. How is that any different from the government clearing those guys to carry guns? Besides...what terrorist where's a shirt saying "HI I'M A TERRORIST!"???
I think it's bullshit, but I'm okay with Delta (non-governmental company) saying we don't want your business. I think he might have a case against them, but whatever. The fact that he was then detained again and repetitively questioned....bullshit.
