This blog is originally from Oscar Lai and here are my comments on this issue.

The Obama administration is now introducing a “Pre-check” program that will filter people according to their potential threat to aviation. This system assures the safety and security of the USA however somehow violated the privacy of those passengers. There might be some passengers who are not feeling comfortable with sharing personal information with the airport but they don’t have a chance to reject this since this is the rule and policy. I understand the purposes behind all these actions, however, I disagree with them.  The USA could have used other methods in order to protect their country instead of taking all these actions since somehow it is not so respectful.
