Wrong. I could demand, as a condition of entering onto my property, that anyone (or everyone) not carry their weapons.
Thus, there would be no real basis or reason to search anyone coming onto your property for weapons, or for any other reason.
My private property rights are more than sufficient.
This would also apply to relativily 'unregulated' airlines, as sneakyypete noted ours once were.
No, it would not.
Amazing how some folks demand absolute fealty to THEIR rights, and demand the privelege of urinating on everyone else's.
