Below is a link to a publication on case law that the Alameda County DA puts out a few times a year. In the latest edition there is a significant article about 'Open Carry Detentions.'
Several cases are cited and I got the impression the DA supported most of the issues that are not clearly defined by case law yet. The basis of the article is a 2009 case out of Springfield, Massachusetts, Schubert v. City of Springfield. However, several other cases are cited.
Read it for yourself.
Alameda County DA: "Moreover, the Supreme Court has ruled that Second Amendment rights are “not unlimited,”
which apparently means that all of the California statutes pertaining to handgun control are constitutional and, therefore, enforceable."
How in the world do you jump to such a conclusion!!! This should be our first clue that the whole article is a "shoot from the hip" attempt to justify illegal action taken against the citizenry. It is filled withsuperficial references to certain out of state decisions applied haphazardly to open carry in California with unfounded conclusions concerning what and what is legal for police to do! This POV is not worth the storage space it is taking up on their server and will cause Alameda County law enforcement to conduct themselves illegally! Obviously put together by a first year law student!
