firstly, I wouldn't call them "dick tracy wannabees' - in israel at least 3 bombings (2 or airplanes and one of an embassy) were stopped by this force, and that is just the ones that are documented and reported.
secondly, I am not talking about amatures, I am talking about training individuals who have good skills of working with people and of identifying what is suspicious and what is normal.
thirdly, I think that americans have very short memories and are being very unrealistic in thinking that the threat is over. the threat is only just begining.
I don't think that we need to change our way of lives or how we are doing things. I think that what is in place in america doesn't work well - having people who barely speak english and make minumum wage check that you don't have nail clippers or a lighter isn't effitient or effective. pulling little old ladies and kids out of line for "randon' checks doen'st do any good. having businessmen take off their shoes doens't do any good.
you could take a person with 20 years expereince teaching high school and teach them, in two weeks, to identify any possilbe terrorists if you wanted to do it in the US. sure, you would end up asking a lot of innocent people for their id, but that would be a very small price to pay.
and for the vast majority of the people here, it would only make things urn smoother and easier.
