Well, that didn't take long - Federal judge stays John Kavanagh's law criminalizing filming the police

Federal judge blocks Arizona law restricting filming of police

A federal judge blocked an Arizona law on Friday that was set to ban the recording of police within 8 feet of a “law enforcement activity.” 

U.S. District Judge John Tuchi granted a preliminary injunction requested by the American Civil Liberties Union (ACLU) of Arizona and multiple media outlets, which argued that the law violates the First Amendment rights of journalists and the public. 

Kavanagh's original bill is here.

As this is just a temporary stay, this isn't over, but it is a good first step.
