Well, I blogged about this back in 2010. My student response was 2 for it and 1 against. A generation of citizens have grown up with War, Terrorists, and no music on MTV. What is wrong with the picture?
Well the TSA will be removing those x-ray scanners from airports because of a loss of privacy. I expect a secure flight, but the whole travel experience has certainly changed over the past decade.
For details from TSA, see the page. You can also see that TSA is privitizing security at airports and we know from jails and schools how good that will be.
