It’s been three days since Attorney General William Barr sent Congress a four-page summary of the “principal conclusions” of special counsel Robert Mueller’s report on the Trump-Russia investigation. That’s not a long time, but it has been long enough for a passionate debate to arise between partisans who have not seen the report, played out for a public that has not seen the report, either. Uninformed arguments are everywhere.

The Mueller report should have been prepared from the very beginning with public release in mind, and then made public the moment its completion was announced.
