A thoughtful a rticle with a good summary of pros and cons. If the USA were less dysfunctional we could hope for positive change along the lines of the Scandinavian countries. But this would require a far better informed and intelligent citizenry, political will, and a great many other elements the USA will always lack. In consequence I think that despite all the temporary outrage and empty promises, things will continue to get worse as the police continue their inexorable descent into being nothing more than heavily-armed rabble acting with complete impunity. Rather like most African armies, in fact.
