As an anarchist-leaning libertarian, I often find myself defending the theoretical view that a statist legal framework of "limited government" and (even worse) "rights" like the US Constitution and the Bill of Rights not only are useless to protect individuals from depredation, but effectively harmful. And then, cases like this happen, in which even though the events unfolded in the most anti-human State in the whole Union, this guy was able to effectively protect his family thanks only to that framework.
I say this because I could find myself in the same situation in Spain, and 100% guaranteed I would end up in jail for simply having my legally owned 9 mm handgun on me at my own doorway.
This video will obviously not change the minds of the anti-human psychopaths who want to ban private ownership of guns in the US, and even less the "Yes Daddy State Police Me Harder" retards in Europe. But it should be food for thought for the pro-human libertarians.
