Picture this -
A major building in a major city burns down. MONTHS later the Fire Marshal says, indignantly, mind you -
"Was it because of faulty wiring or an arsonist? What difference, at this point, does it make?"
Would you accept that? Would it make any sense at all with the next sentence -
"It is our job to figure out what happened and do everything we can to prevent it from ever happening again."
First off, it's contradictory. The cause doesn't matter, but now we need to "...figure out what happened..."
Well which is it dipshit? We need to figure it out or it doesn't matter? Pick one.
If you wouldn't accept it from my fictitious fire Marshal, why would you accept it from the Secretary of State regarding Benghazi.
In typical understatement My Bad Boyfriend said to the SecState "“frankly, the answers that you’ve given this morning are not satisfying to me.”
