I wish it were that easy. The fact of the matter is that gun control has proceeded from exactly such incremental means in the areas cited and some others beside: Great Britain, New Zealand, Australia, Canada, and even here in New York and California. Unfortunately, the clear pattern on the part of gun controllers and legislators in general in those areas is one of uniform deception, consistent misrepresentation, and ultimate betrayal of the very trust that the author suggests such a Supreme Court decision would engender. It is a sad thing to say, but such a Supreme Court decision is no protection against executive orders that must be challenged in court at great cost in order to overturn. It offers no protection against the cleverly-worded state and local ordinances passed to accomplish one thing and enforced in an entirely different direction, "stretch[ed] as far as I possibly can," in that master prevaricator Bill Clinton's words. In short, the trust is gone, and rightfully so.
Yep. Various legal dodges were used to prevent blacks from voting for a century, notwithstanding the plain and unambiguous language of the Fifteenth Amendment. Gun grabbers have the same low cleverness as their Jim Crow soulmates.
That's one of the biggest misconceptions around. "Executive Orders" only apply to employees of the Executive Branch. The President cannot order private citizens who are not employees of the Executive Branch to do anything. The orders don't apply to you. They are just what they say. They are "orders" to Executive Branch members to do something. The President can order the members of the Executive Branch to (attempt to) confiscate your weapons, true, but he cannot order you to turn yours in.
