The only "Unarmed" people are peopel who lack imagination and knowledge. The government can ban guns, knives and explosives, but anyone with a brain can make hundreds of lethal weapons from common household items. It could be a lethal mistake to assume that because someone doesn;t have a knife, gun or pipe they are unarmed. As long as someone has a functioning brain, they may be well armed.(this excludes politicians and lawyers, naturally).
Personally I like the blowtorch, but it is far more impressive on capacitors than memory. I don't know enough about the chips to be sure about this, but I suspect the hammer method is enough to discourage anyone but serious government angencies, and I would hope none of you would have anything on your computers that would warrent that kind of scrutiny. I know I don't, although with the RIAA, one never knows thses days, they have been known to subcontract out to some shady characters.
