San Fransisco is NOT part of the United States. As far as I am concerned it seceded when the city government voted to give AWOLs "sanctuary" during Gulf War I.
I agree, it is NOT part of the United States. They are now banning JROTC. A scenario I would love to see: SF gets hit by terrorists and before the detested military could arrive to help, a quake would finish them off and the place would drop into the ocean. One final wish: All the liberals in the area be congregated in one place.
