There's a diagram of a pipe bomb on the CNN web site, in the story about the horrible things.

In case you want to see, check it out at: http://www.cnn.com/US/9607/27/pipe.bomb.explain/index.html The picture that is on the page gives enough information for the average person to go to the hardware store and buy the parts..... Not only do they HAVE to point out that the information is available, but also provide it. *NOW* who is irresponsible? Seth
