Hopefully, by the time you read this, the riots now wreaking havoc in dozens of US cities will be history. Tempers will have calmed, cities will have started rebuilding torched neighborhoods, and the legal system will be hard at work meting out justice for the horrific death of George Floyd, the African American whose death touched off the rioting. This is the best possible scenario. The worst case makes our current problems look like a picnic by comparison.
