If Strzok’s texts reveal deep animus towards Trump or an operational effort to tilt one or more investigations, then all of his actions have to be reviewed to assure the public’s confidence in the bureau. That one or two agents or officials of the bureau are discovered to have been acting from improper motives would be bad enough. To try and sweep those activities under the rug would be worse. Against the backdrop of other recent controversies, it would be disastrous.
Step one is a quick publication of the questionable texts. All of them. The public has a right to know what the predicate for Mueller’s extraordinary action was. The public also deserves a detailed account of Strzok’s (and Page’s) duties and authorities during the years in question. If an NBA official was discovered to have purposefully thrown even one game, every game in which he had carried a whistle would be under the microscope. That’s how it works.
Unless there’s a coverup.
