Twitter on Monday was all-United, all the time -- and it sparked some interesting talk about power, class, and the use of force to protect capitalist operations in this country. Still, it all seemed a tad ironic; this is a city where police officers had been accused of torturing criminal suspects, in addition to several questionable or worse police-involved shootings. Those things have also caused some buzz, but nothing compared to an incident on a pricey domestic flight, involving a medical doctor, recorded and posted by folks on their state-of-the-art smartphones. You had to wonder if the real news here was the brutality of modern-day America getting real enough to finally hit a nerve for the elite professional chattering classes.
