See, this is where I disagree. People motivated at flouting the system will find a way. There is already speculation that non-metallic guns have been developed. And while you may have "subverted" the system on two occasions, well, you are white are you not? I don't really think that the argument that using stereotypes being efficient is a very strong argument. That's like saying that dynamite fishing is a good way to fish because the total number of fish 'caught' using this method is higher than more targeted methods. While it may be true that catching persons of interest is vital to national security, but I am willing to wager that they have "caught" far fewer legitimate persons of interest than they profess to have at the cost of banning a much higher number of people from flying. Yeah, not flying at all is safer than flying, but not living is also less risky than living.In 1995 it was pretty easy to bring a gun on a plane, for anyone, and now it's almost impossible!
