Is the situation different in other states that do have concealed carry laws?
It means a person can get a license to carry a concealed gun on their person. Typically it requires a bit of training and a test. I live in a more free for all state, and you can get a CCW with a couple Saturdays of class and a hand gun shooting test.
Some states allow you to protect property with deadly force and others do not. You have to read state law to understand the nuance.
In San Francisco you can generally take anything you want from anybody and the victim will generally get in trouble trying to stop you. You may get arrested for the crime but there is no guarantee. The police will release you soon after you are arrested, often on a signature bond with zero deposit [1]. You can rinse and repeat this process dozens of times per year because it is unlikely you will spend any significant time in jail or prison. You'll have a database record but no problem making ends meet upon release.
Sounds like what happens to the rich and well connected when they get in trouble with the law. Seems like equal justice to me.
California doesn't allow 'open carry', which many other states do. This allows you to carry a pistol in a holster outside of your jacket/shirt so that it can be seen.
