SAN FRANCISCO: Thousands of Californians hoping to carry concealed guns may be out of luck. That's because a federal appeals court says California can require gun enthusiasts to provide a good cause for wanting a permit to carry a concealed weapon. That law was briefly struck down in 2014 by the same court, and some county sheriffs loosened their permit restrictions. San Diego collected applications under the looser restrictions, but didn't act on them while awaiting the court's to sort out the issue. The San Diego sheriff says the 2,463 applicants applying under the looser restrictions won't be given a permit unless the U.S. Supreme Court overturns a 9th U.S. Circuit Court of Appeals ruling Thursday.
