"Split Ninth Circuit panel stays Arizona execution based on First Amendment (really?!?!) drug secrecy concerns"

Yeah, I don't really buy it either, though think secrecy has due process problems. (More here on challenge overall -- valuable stuff but still don't think the 1A claims work) As to Judge Kozinksi's dissent, the problem is people don't want to "stomach" the firing squad. I'd add it is probably a bit too direct for some people. If we execute, it very well might be better than lethal injection for the condemned. But, various things go into acceptance of a punishment.

Update: The USSC didn't buy it either though multiple justices voiced concerned earlier on other grounds. Meanwhile, a footnote among the summer orders.
