I got this from ABC news ( Ill post the link) just food for thought....they world is not safe and the others aint plaing nice. http://abcnews.go.com/sections/wnt/DailyNews/bombmaking_video020617.html Bomb-Making 101 Hamas Militant Group Provides â€˜How-toâ€™ Video for Constructing Explosives By Dan Harris J E R U S A L E M, June 17 â€” A chilling 3 Â½-hour videotape obtained by ABCNEWS features what the Israeli military calls "Bomb-making 101" for Palestinian militants. The tape starts with a masked man â€” who says he's a member of the military wing of the Islamic militant group Hamas â€” giving a brief lecture on the importance of waging holy war against the Israelis, and the heavenly rewards awaiting those who make and explode bombs. And then the lesson begins. Standing at a white board, the bomb-making expert uses diagrams and high school-level math to explain how a bomb works. Speaking slowly and simply in Arabic, he then shows how to cut the wood that will serve as the shell of the bomb, and the copper foil that will cradle the explosives. He repeats himself often, so as to better drive home his points. Almost all the necessary material, he says, is easily acquired at local stores, including test tubes from a pharmacy, ball bearings from a mechanic and wiring from an electrical store. "It's really 101 â€” how to make an explosive bomb by the Hamas," said Col. Miri Eisin, a senior Israeli military intelligence analyst. She says the Israeli army confiscated the tape during an invasion of the West Bank city of Nablus last April. Nablus, she says, is known as one of the major centers for bomb-making. â€˜My Brother Fighters â€¦â€™ Eisin says Hamas has the most sophisticated bomb-makers. Hamas claimed responsibility for a March suicide bombing that killed 29 people and wounded nearly 100 as they celebrated Passover in the Israeli coastal resort town of Netanya. As the tape continues, the bomb-maker says: "Now my brother fighters, we put the shrapnel in the case â€¦ It's better to use ball bearings than nuts." They're more deadly and destructive, he explains. Then come the explosives: specifically, nitroglycerin. This is one ingredient that is hard come by â€” it's usually smuggled in from Egypt or stolen in Israel. "We can only fit 7 kilos," the bomb-maker says as he loads the explosives into the bomb casing. "We were hoping to include more." There wasn't enough room. Finally, the bomb-maker explains the electrical wiring, which includes the detonator made out of a small household drill. "Now the bomb is ready," he says. He even provides a list of preferred targets: cars, bus stations, markets and military bases. He also uses a diagram to show where to place a roadside bomb in order to kill the most Israeli soldiers or settlers on a bus. Eisin says the tape appears to be meant only for Hamas militants. It comes at a time when the Israeli army is successfully arresting and assassinating top Hamas bomb-makers. "There are more potential suicide bombers today than there are people who know how to make explosives," said Eisin. "And that's probably why they made the tapes." They want to make sure that their deadly expertise survives, even if they don't.
