California police unions are preparing to battle new transparency law in the courtroom

Just as a landmark police transparency law is going into effect, some California police agencies are shredding internal affairs documents and law enforcement unions are rushing to block the information from being released.

The new law, which begins to unwind California’s strictest-in-the-nation protections over the secrecy of law enforcement records, opens to the public internal investigations of officer shootings and other major uses of force, along with confirmed cases of sexual assault and lying while on duty. But the lawsuits and records destruction, which began even before the law took effect Jan. 1, could tie up the release of information for months or years, and in some instances, prevent it from ever being disclosed.
