Now They Want to Confess?

So the brains behind the September 11th attacks, currently being held at Guantanamo Bay, finally want to confess to conspiracy charges. They announced this infront of the family members of the victims that perished in the attacks.

There are also a couple co-conspirators that need phych evaluations prior to accepting the confessions... (A COUPLE?)

I ask... WHY NOW???

Interestingly enough, Obama team considers changing interogation policies...
