Ari Ezra Waldman gives a good legal analysis of the Indiana RFRA and why we shouldn't settle with changing it, we need to change the federal RFRA as well. His conclusion:
We may win "clarifications" of Indiana's RFRA to make it more like the federal RFRA. That's not a victory. In fact, it's much more dangerous: it implies that the federal RFRA is a good thing that we're willing to accept. It isn't and we shouldn't.
