Federal agents faced gunfire just after 6 a.m. Wednesday in San Diego County as they approached a suspected Mexican Mafia-tied drug network, announcing themselves before a short exchange of shots. Authorities arrested 35, served 10 warrants, still sought seven fugitives late last week after 42 Justice Department indictments of alleged San Diego County gang members and associates including Poway's Varrio Hidden Hills, accused of moving large methamphetamine and fentanyl quantities. California has the nation's strictest gun laws covering assault weapons, magazines, registration, ghost guns, concealed carry, school and campus arming bans, and ammunition, yet agents still met gunfire on duty.
