Yeah well, about Mikhael Kalashnikow. He build the famous AK47 for Stalins UdSSR. NKWD, Gulags, etc. were active since many years by that time, organized state-terrorism against anyone opposed to the glorious soviet system and their leader ... in other words, his words sound quite hypocryte. But when you consider your system belong to the good ... you probably close your eyes to everything else.
But I go along with Einstein. The more technogy is avaiable to the masses, the more powerful a single persons becomes. There might come a time soon, when anyone could just tinker a atomic bomb together in his garage ... we seriously need to change our way of thinking, till that happens.
