I hate to argue against you because I agree that nobody needs a hundred round clip or full auto for an intruder, but the forefathers’ intended right wasn’t “people should have muskets”. It was much closer to “the people should be armed in case of tyrrany by their government”. The intention was for people to defend their other rights by force, making it more difficult for the government (or an invading force) to take over (this was immediately post-revolution mind you and much of the bill of rights was in direct response to british soldiers’ activities). Of course they also thought we’d be reforming the government and drafting new constitutions as the culture changed, but of course that never happened.
I am not a historian, just a pedant.
I’m guessing this judge considers the telephone to be an example of negligent design as well. After all, the phone company doesn’t record every phone call I make and disconnect me if I mention an illegal drug.
