How widely will this be covered?

This couldn't happen a minute too soon:

On February 25th a group of eleven renowned law professors from around the country sent a letter to Arizona Governor Jan Brewer (R) warning that SB1062—the bill "which amends Arizona's Religious Freedom Restoration Act" (RFRA)—has been "egregiously misrepresented by many of its critics." 

The mix of eleven professors consists of Republicans and Democrats, religious and non-religious, "some...[who] oppose same-sex marriage [and] some... who support it." Their letter was obtained exclusively by Breitbart News ahead of its public release.

Their letter focuses on the important role RFRA plays in "[enacting] a uniform standard to be interpreted and applied to individual cases." And the professors said such a "standard makes sense" as "we should not punish people for practicing their religions unless we have very good reason."

SB1062 amends Arizona's RFRA in two ways: 

1. "It provides that people are covered when state or local government requires them to violate their religion in the conduct of their business."

2. "It would provide that people are covered when sued by a private citizen invoking state or local law to demand that they violate their religion."

Countering misrepresentations, the professors pointed out that "SB1062 does not say that businesses can discriminate for religious reasons."

In concluding, they urged Gov. Brewer to be sure SB1062 is "accurately considered," so that in passing judgment on it she is not "misled by uniformed critics."
