There are appropriate places to open carry loaded handguns already. The proposed ban on unloaded open carry of handguns has no effect on those areas. Carrying loaded will run you afoul of 12031 and carrying unloaded will run you afoul of AB144-- (whatever the PC numbers it), in those places where the prohibiting codes apply.
We need to attack this more from the flanks rather than head on... that is to say, 12031 will need to be challenged in a venue and circumstances where we can predict the outcome with some reasonable accuracy. The circumstances would be some illegal search and seizure pertinent to 12031 in unincorporated territory where discharge has not been prohibited by local ordinance and in the jurisdiction of the Federal Court in the Eastern District of California.
I doubt that any other location and any other circumstances would net us the desired result... Carrying loaded where it is illegal will only disqualify you from further exerting you 2A rights.
I appreciate your enthusiasm. I share it.
