While we are on this topic, what I find to be a complete sham is TSA-PRE (a US preflight registration program). The pre-screening is valid for 5 years, in exchange you don't remove your shoes or have to remove electronics and liquids. Basically, what you did BEFORE the TSA program was put in place.

I presume they are OK with taking the chance that a TSA-PRE enrolled individual is not turning into a shoe-bomber in year 3 after preenrollment? Why not just abolish all the checks and selectively pull people to remove liquids, shoes and electronics. You'd lose the $99 revenue/passsenger that TSAPRE generates.
