Security by Obscurity
Reminds me of the US where they have successfully sold this stuff as keeping people safe (I.E. preventing crime), but strangely enough I have not heard of one single case where the searching of electronic device prevented a crime. I have heard of numerous where it "caught the criminal" after the fact. Me thinks that too much information can get in the way of actual crime prevention, especially if the parser does not know what to look for....
