@freemo For people who complain about dangerous objects, it comes in handy to point out the early 20th century.
You could buy dynamite at the hardware store, buy opium or cyanide at the drug store, and order a machine gun through the mail.
And yet society was more peaceful than it is today, at least until radicals from the failed 1905 Russian revolution started showing up here. Whatever has gone wrong, it isn't dangerous objects.
@freemo Fortunately "Bond villains" or people who are willing and able to spend a long period of focussed, intelligent effort planning something evil, are relatively rare. Anders Breivik comes to mind, and he published a very detailed how to journal. So far as I know, nobody has followed his formula.
I just think the fear of dangerous objects thing has gotten absurd. In the UK you can get an actual court order forbidding you to own a kitchen knife.
