> Telling someone how to modify a semi-automatic gun to be fully-automatic? Almost all such "instructions" don't actually work. (It's a near-perfect form of consumer fraud because you can't complain to the FTC or police when the instructions don't work.) Note that you can also tell people how to make poison, explosives, overthrow a govt, speed, rob a bank, and so on. (The conviction in the "hit man manual" case appears to have been an exception.)
