The Justice Department sued the Los Angeles County Sheriff’s Department on Tuesday, accusing the agency and Sheriff Robert Luna of systematically violating the Second Amendment rights of residents by dragging out concealed carry permit approvals for months or even years.

In a lawsuit filed in the U.S. District Court for the Central District of California, the DOJ’s Civil Rights Division said the sheriff’s department approved only two concealed carry weapon permits out of more than 8,000 applications over a 15-month period. Some applicants were scheduled for interviews as late as two years after submitting completed forms, the complaint alleged.
