Tex, we have been through this time and time again. I state on virtually every thread like this that the government has the legitimate power to ban the possession of two items - weapons of mass destruction and child pornography. WOMD are not used defensively, and individuals do not have the right to engage in war with other countries. Children can not consent to sexual activities, thus child pornography is a crime, because the child is the victim.
or your nighbor aiming a loaded weapon at your child?
That is a direct threat of force. No libertarian would argue that this is not a crime.
It is all risk, no harm.
No, they were both a threat of force, a violation of rights.
