A version of "Name That Tune" with respect to opinions from the California Court of Appeal would be to attempt to accurately and summarize the thing in as few sentences as possible.
For this opinion from today, I can Name That Tune in a single sentence:
The evidence isn't insufficient as a matter of law to keep someone detained as an SVP when he's a repeat child molester who forthrightly admits that he can't guarantee that he won't molest another child upon his release, even though most -- but not all -- 74-year olds don't have the energy and desire to keep molesting kids.
Justice Yegan also keeps his opinion short -- around three double-spaced pages (including a reference to Steinbeck) -- but that single sentence pretty much says it all.
