They are too late, the records was proven forgeries on my fourm around 4am. tsk tsk why can't CBS first do a simple smell test before they report something?
1. Rather & staff wanted the docs to be real so badly that they deceived themselves
2. Rather & staff know for certain they were forgeries but nonetheless went to air with them intentionally
3. Rather & staff participated in the forgeries
When the force of this reaches critical mass, Rather will fall back on a modified number 1, saying that their source was extremely credible and they were fooled. They will refused to expose their source. (No way they'll out a Kerry-Edwards staffer.)
I suspect that they did give it the smell test. I also suspect that they were hoping that nobody else would.
