This is one of the greatest letters ever written by a public servant. You can read this twenty-five times and still not get what is happening here.
That's right. Nothing.
This is how someone uses formal communication to assure people that absolutely nothing is happening.
Now, if there was something happening, the Chief of Police of Columbia, South Carolina probably would have said so in this letter. But, instead, he says a whole lot of different things, and even quotes Walter Cronkite, but says exactly nothing that will
- lead people to believe something is wrong
- get him in trouble
- whip up public sentiment
- anger his bosses
It's a masterful piece of work, and it was probably vetted by a darned good lawyer.
