"You seriously try defending reading bomb-making books?" I occasionally read bomb-making books. In part because I once had a job that involved explosives, so I'm interested in high energy engineering, and in part because I'm curious about how IEDs are constructed, so as to consider how one might detect and defeat them. I don't have a current employment need for this information. I'm simply curious as a matter of physics, engineering, and keeping myself informed about technology that influences events to some degree. Given my interests, it appears that you'd shop me to the authorities because you regard those interests as suspicious. That's unhelpful to society, to say the least. And illustrative of your misapprehension of actual risk.
