Yep, the x-rays would be a very good way to go. ALSO, it is simply time to stop the Political Correct idea, and begin to aggressively profile potential threats. IF folks who fit the profile of terrorists don't like it, simply don't fly. For the very life of me, I simply cannot understand what is evil about profiling..Isrealis use it ( along with other methods ) very sucessfully.
As far as profiling goes, ok, I"m a 60 year old white male. Lets say, for instance, a young child was last seen being lured into a vehicle driven by a 55-65 year old white male, and that vehicle was somewhat similar to what I drive. I would have simply NO PROBLEM being stopped, I.D.'d, and briefly questioned about my activity. If the child came up missing a reasonably short time prior to my being stopped, again, I would have NO PROBLEM with my vehicle being searched. It is exigent circumstance..no warrant is needed.
It is simply way past time to get serious, and treat the threat accordingly.
