..Can I get a confirmation of OC law related questions please...
1. While an officer (in CA) may "ask" for an individual who is engaged in the "open carry" of a firearm to present their ID, compliance is NOT required assuming the "open carry" of the firearm is being conducted in a legal fashion. California has no "stop and identify" statute. Unless you are operating a motor vehicle or are under arrest, you are not required to give your name or show ID.
2. While an officer (in CA) may "see" the serial number of a firearm while conducting a 12031(e) inspection to verify that the firearm is unloaded, they may not "search" the weapon for the serial number. Theoretically. Once it is outside the holster, however, LEOs will argue that the serial number (if visible on the exterior of the firearm) has now come into "plain view"
3. The "covering" (in CA) of the firearm serial number (ie: electrical tape) is NOT illegal, and is not considered destruction of the firearm serial number. 537e. (a) Any person who knowingly buys, sells, receives, disposes
of, conceals, or has in his or her possession any personal property
from which the manufacturer's serial number, identification number,
electronic serial number, or any other distinguishing number or
identification mark has been removed, defaced, covered, altered, or
destroyed, is guilty of a public offense
4. Should a firearm be discovered (in CA) to have a "covered" serial number during a 12031(e) inspection this does NOT create probable cause or reasonable suspicion to detain an individual for any longer than is necessary to conduct the 12031(e) inspection. See 3.
5. Audio & video recording of any personal interaction with LEO's (in CA) is completely legal with NO requirement for the individual to inform LEO's that audio & video recording is being conducted. Only conversations where there is a reasonable expectation of privacy by one party are subject to the prohibition, as I understand this.
6. There are no laws, regulations, ordinances, etc. within the, City of El Cajon, County of San Diego, or City of San Diego, that restrict the "Open Carry" of a firearm further than what is currently restricted via California state law. Study the municipal codes.
