The Lack of a Tape and Impeachment

One of the things lost in the current discussion over impeachment of the president is this difference from the Watergate era:  in Watergate, we started with a crime, a clear violation of law, burglars discovered red handed.  From that crystal clear focus the story expanded in multiple directions--before: why were they there, what was their aim, who commissioned them, who would have benefited and after: who paid for their defense, for their silence, who was covering up the facts, who lied.

By comparison in the current situation, as in the case of Clinton, we don't have a crime as clear as burglars caught in the act.  So the narrative starts blurry, and gets blurrier, because there's no foundational fact which no one can dispute.

And what was the fact in Watergate and not in the others: the tape on the door which guard Frank Willis discovered and removed, only to find the lock retaped.
