How does a man getting 'high' in private 'endanger' his neighbor? What potential for harm, what clear & present danger is there?
Try to come up with some reason to stop him, prior to any violent act that takes into account the rule of constitutional law, please.
"Is it a violent act to aim a gun at someone's head and not firing? Danger is potential for harm. Once you have acknowledged that a certain amount of danger merits gov. intervention, you must then leave it to the states. If you don't acknowledge that, then you would support the personal ownership of nuclear weapons."
Answer the guestion, please,
