I guess some chiefs just like to be sued. Too bad they can't pierce that immunity barrier and go after the chief's personal assets. That's about the only thing that would stop this sort of abuse.
Seems "simple" to me. We need to draft legislation which would hold public officials personally responsible for obvious and reprehensible violations of the constitutionally protected rights of the people in the areas the officials have direct control of.
An officer intentionally threatens to arrest someone for something which is lawful, such as passively recording a situation, they are on the hook for any judgement. This does not exclude the possibility of liability on the part of the town or agency the official works for.
A chief flatly refuses to comply with the law with regards to the issuance of LTC or FID, they are personally responsible under 42 U.S. Code § 1983 as they are depriving someone of their rights under color of law.
Simple (in theory)
