The scuttlebutt on Calguns suggests that the judge who made this ruling has a CCW permit. Interesting that his unloaded, open carry argument seemed to be partially based on an individual "...being able to quickly load their firearm for self defense use".
The Supremes in Heller ruled that even with locked doors, windows and walls buying you time to react that requiring
unloaded storage was
not acceptable for self-defense.
The judge just tacitly acknowledged bearing as part of the right. If OC survives the appeal on this, if it can still be made, would open up that argument to carry where you have even less time to react.
