The basic theme of the article is that the inability or unwillingness (often under standdown orders from politicians) of law enforcement to protect life and property during the summer 2020 riots and looting in cities across the country undermines the claim of opponents of the right to keep and bear arms that individual firearms ownership is obsolete given the existence of modern police forces.
One contribution the article makes is to document the scope of the lawlessness last summer, which was largely ignored by the media. The article did not attempt to be comprehensive, but it may still be the most thorough discussion of the extent of the unrest, the lack of police response, and of efforts by citizens to protect themselves with firearms.
You'll love the idiot take from the two idiot professors from Duke and Yale who try to equate defending yourself from rioters as being 'coding racial justice protests as crimes'.
I think it was George Orwell said "There are some ideas so absurd that only an intellectual could believe them."
And I'll bet these two think socialism is a wonderful idea, too.
