Sure, the California Supreme Court is left-leaning in a lot of areas, but sometimes when reading an opinion (or otherwise), you don't need a weathervane to know which way the wind blows.
Here's a test: See if you can fill in the blank for the next word in this opinion, the first paragraph of which reads (in its entirety):
"A jury convicted Manuel Bracamontes of the first degree murder of nine-year-old Laura Arroyo, with special circumstances for committing the murder while engaged in kidnapping, lewd act on a child under 14, and oral copulation. A death sentence was returned and imposed. We _______."
Do you think the omitted word is (A) Affirm, or (B) Reverse.
Yep. You're right.
