This guy is clearly a mental patient. First of all, have ANY of these devices been determined to be real (capable of actually exploding)? Sounds like a sick joke to me. First of all, the guy goes out of his way to make a device that SCREAMS "bomb". No joke, any kindergartener could identify these devices as being bombs. Explosives experts are laughing as we speak at the design of these so-called "pipe bombs". One expert used the adjective "silly" to describe the wire going in both ends.
This crazy loon might as well have taped together a bundle of 7 road flares, and strapped an old-timey analog alarm clock (with 2 bells on top) to it -- you know, like in the cartoons and clipart. His "bombs" couldn't get any more stereotypical -- or ineffective. Has anyone figured THAT out yet? Is this guy mental, or what?
