(a) Nothing in this chapter precludes a law-enforcement officer from removing a firearm, projectile weapon, or ammunition under other authority or the filing of criminal charges when probable cause exists.
(b) A law-enforcement agency is immune from civil or criminal liability for any damage or deterioration of a firearm, projectile weapon, or ammunition stored or transported under this chapter. This subsection does not apply if the damage or deterioration occurred as a result of recklessness, gross negligence, or intentional misconduct by the law-enforcement agency or federally-licensed firearms dealer.
