Arizona makes it illegal for bystanders to record cops at close range | Ars Technica

I'm not saying you can't video police. Just stay back a few feet in some situations --USA TODAY

This amends Arizona Law, Chapter 13, Section 37, and is warned when police officers are aware that they are engaged in law enforcement or are within eight feet of reasonably aware. It is illegal to continue video recording.

If law enforcement activities are carried out within a closed structure on private land, those authorized to be on private land will be deemed unsafe by law enforcement officers to interfere with or be present. Unless ordered to leave the scene, it is permissible to shoot video from a room or location less than 8 feet in contact.

Persons who are subject to police contact can shoot video as long as they do not interfere with their actions such as physical examination, alcohol check, or handcuffs. This also applies to car occupants who have been ordered by the police to stop.

Arizona Parliamentarian John Kavanagh, who promoted the amendment of state law, said it was important to create a buffer zone to prevent police officers from being attacked by unruly bystanders. 'It's ridiculous to claim that shooting from 8 feet away doesn't give the right footage,' he said, dismissing criticism that he should be closer to law enforcement.
