Instead of finding a solution, such as "it happened, it just happened, learn from are mistakes'', that cant work out between these guys. All there doing is pointing fingers.
IF somebody's negligence contributed to the catastrophe, then that's a pretty good lesson to be learned. The commission will undoubtedly report on whether or not blunders were made, and if so, then by whom.
Was it like this today back in the 1940s when pearl harbor hit ??
It's not like the commission is the only response to what happened. If they stopped the country in its tracks, ignored all other matters and just focussed on allocating blame, then that'd be a serious error. However, the current commission is not impeding ongoing operations, in fact it's been two and a half years since the crime, so it's a safe time to take a look at what happened and why.

If a criminal escapes from custody, you don't just say "it was all the criminal's fault" and ignore the possibility of gaping flaws in the system; common sense demands and inquiry. I believe the same principle applies.
I just really don't like the way that author was saying the executive should be above criticism if it'll "make the country look bad", that was the frightening part of the article for me.
