I’m a bit confused with regards to the London train bombings.
Does this look like it can do this? Or this?
Those weren’t nail bombs on those trains, guys. Sure anyone can make a nail bomb, but nail bombs aren’t designed to do structural damage such as blowing off the roofs of trains and buses. Nail bombs hurt people, and they are designed to maim, not to kill (as a larger bomb might and did).
This is just odd. Why would terrorists with the capability to do tremendous damage with military grade explosives waste their time with nail bombs and detonation cords?
