We see Google experimenting in so many places outside of its core search and advertising business, whether that's bringing broadband Internet to the world or funding an entirely separate company to pursue solutions to disease and mortality. Amazon's one of the few other companies that thinks as big as Google does.

There are lots of retailers that are now scrambling to emulate the Amazon model, so Amazon does not have a monopoly on same-day distribution or broad selection or low prices. All that said, there are advantages that accrue to the largest player, so I don't see much in the way of Amazon slowing down.

Those of us in law enforcement must redouble our efforts to resist bias and prejudice. We must better understand the people we serve and protect - by trying to know, deep in our gut, what it feels like to be a law-abiding young black man walking on the street and encountering law enforcement. We must understand how that young man may see us.
