We know from United States v. Garcon that in the 11th Circuit "and" means "and" for purposes of the safety valve provision of the Sentencing Guidelines. (Another case involving the same issue was argued earlier this Term in the Supreme Court.)
Despite the en banc 11th Circuit already saying "and" means "and" for purposes of the Sentencing Guidelines, federal prosecutors and probation officers are taking the position that the word "and" means "or" in the new "Zero Point Offender" sentencing guideline provision, which provides that if you have no criminal history, you receive an additional two level reduction so long as certain other conditions are met. One of the conditions is that:"(10) the defendant did not receive an adjustment under §3B1.1 (Aggravating Role) and was not engaged in a continuing criminal enterprise, as defined in 21 U.S.C. § 848." (emphasis added).
Statement of Chief Justice John G. Roberts, Jr.:
A daughter of the American Southwest, Sandra Day O’Connor blazed an historic trail as our Nation’s first female Justice. She met that challenge with undaunted determination, indisputable ability, and engaging candor. We at the Supreme Court mourn the loss of a beloved colleague, a fiercely independent defender of the rule of law, and an eloquent advocate for civics education. And we celebrate her enduring legacy as a true public servant and patriot.
UPDATED -- Thanks to a commenter for pointing me to this AJC article, which quotes Judge Jordan extensively about Justice O'Connor (he clerked for her back in the late 80s):
He fondly remembered being invited to her Chevy Chase home in Maryland most Saturdays, when O’Connor would cook while discussing the following week’s cases with her clerks.
Tex-Mex was usually on the menu, Jordan said.
“The stuff that she made for us was very, very good,” he told The Atlanta Journal-Constitution. “Tacos, burritos, nachos. Things like that. It wasn’t all exclusively Tex-Mex, but that was, I think, the majority of her repertoire.”
On the occasional Saturday spent working in O’Connor’s chambers, Jordan said she would bring food from home. He said the weekend conferences were a special time for the clerks as O’Connor shared her detailed thoughts on cases.
