A Rafsanjani Ultimatum?

Scott Lucas is keeping tabs on an "extraordinary" report:

... Rafsanjani had asked the Supreme Leader to arrange for the release from prison of Alireza Beheshti, Mir Hossein Mousavi’s advisor and the son of the late “martyr” Ayatollah Beheshti. This evening, whether or not it was because of Rafsanjani’s intervention, Beheshti was freed. There was more, however. Rah-e-Sabz claimed that Rafsanjani had given an “ultimatum” to Ayatollah Khamenei to act against the post-election abuses.

We are still treating the story with caution; however, an EA correspondent has considered the implications if the report is accurate.
