Police officers wearing body cameras has been more and more common. This published opinion from 4/1 here (In re Edgerrin, 271 Cal.Rptr.3d 610) on page 11 makes clear that a there was a detention. Perhaps body cam shots will become more and more common in decisions. And nice color photos could be useful in many opinions.
Other points to like about this opinion include: (1) oversized footnote numbers, and (2)Justice Dato "takes the somewhat unusual step" of penning a concurrence to his own majority opinion "to add a few personal observations."
