I received this in an email from a friend; I do not know its origin:

Here's a solution to all the controversy over full-body scanners at the airports:
 
All we need to do is develop a booth that you can step into that will not X-ray you, but will detonate any explosive device you may have hidden on or in your body.  The explosion will be contained within the sealed booth.
 
This would be a win-win for everyone.  There would be nothing to do with racial profiling and the device would eliminate long and expensive trials.
 
This is so simple that it's brilliant. I can see it now:  you're in the airport terminal and you hear a muffled explosion.  Shortly thereafter an announcement comes over the PA system; "Attention, standby passengers! .............  ...........We now have a seat available on flight number...”................!
