Detectors are just one step in the war, and to add - once a person enters the detector, then all articles carried prior to the detector, are placed in a plastic pan that is sliding through the x-ray machine. If these things keep airlines safe, and federal buildings safe, and state fairs safe or concert's safe, then we somehow can't figure out how to get our schools secure ?? Why so egar to just give up like that ?? It can be done, but it will just show exactly how or where the nation's priorities are anymore.
