No one likes wiretaps, but the D.C. Circuit isn't particularly fond of wiretap warrants which are facially deficient. And the remedy in U.S. v. Glover was a new trial.
You can't exactly blame the court for its inclinations; an obviously legally lacking warrant that is executed to spy on domestic suspects isn't exactly the fantasy of any enlightened democracy.
So why exactly did the D.C. Circuit knock this case back to trial?
