Why Dump The Documenters?

The US government's Iran Human Rights Documentation Center, which has investigated the torture and abuse of protesters since the June election, just had its federal funding yanked.  Massie is beside himself:

As readers know, in general terms I think the Obama administration has taken a fairly sensible, moderate approach towards the Iran. Nevertheless, it's possible to take this too far. And this seems, on the face of it, to be one example of when carefulness crosses the line and becomes craven [...] There are excellent reasons for not being seen to fund opposition groups inside Iran since American funding can only prejudice their cause. But this seems a rather different matter. Perhaps there's an innocent explanation but if so it would be good to hear it. Because otherwise this looks shabby and, actually, terrible.
