Surrendering my 4th amendment rights should not be a condition of travel within the United States.
With strengthening of cockpit doors and revised flight procedures to restrict cockpit access, the likelihood of a hijacking being leveraged to use an aircraft as a weapon has been drastically reduced. Couple that with passengers' realization that compliance with terrorists is not in their best interest, the probability of any future airline attack causing more casualties than the passengers and crew on board is near nil.
This means that airplanes are not unique from sports stadiums, shopping malls, trains, buses, subways, cinemas, or hundreds of other kinds venues where inflicting hundreds of casualties is possible.
We cannot create a police state where every citizen must be viewed naked or sexually groped in order to venture into public places. Stop the Security Theater with airplanes and the inconvenience to millions of people who must fly for their jobs every week.
You can give your feedback to the TSA, too. I did.
