The Isrealis have been doing this a whole lot longer than we have. Right now, the controls that we have in place are really just designed to annoy people (I've never heard of anyone being attacked with nail clippers, for instance....). Bringing in some people that really know what they're doing is a good start, IMHO.
Analyzing the people that are actual threats (PROFILING!!!) is a good, IMHO. Maybe this will introduce a little sanity....searching little old ladies and 6 month old babies because people "need to be randomly selected..." might finally go away.
Of course, this *is* the TSA. I'm not sure that some the people I've dealt with in Airport Security could find their own ass with both hands and map in broad daylight.
Yes they have, and with very great success.
'sok, they only need to find your ass...
