As long as the US federal government-- which gets any imagined legitimacy for its existence from the US Constitution-- exists, there can be no real, binding law concerning arms (weapons), nor will I pretend there is.
For that matter, even after the US feral government is gone, there can be no real, binding law concerning weapons. No matter where humans or their descendants exist. It's a natural human right for a reason.
I was thinking about this while shooting with my son this past weekend. At least I had a nice range day before the bureaucratic failure of a doctor's appointment on Monday, which I may talk about later when I'm less angry. I hate bureaucracy in all its forms more than I can humanly express, which is one facet of why I hate political government so intensely.
If anyone wants to donate to help me replenish what I sent down range or to help with the porch cats, it's always appreciated, but even more so in trying times.
