A photographer who snapped a photo of a group of Oakland police officers was ordered to move behind some imaginary line.

The photographer started walking backwards asking “what line” with the cops moving towards him in an aggressive manner.

They kept telling him to move back, which he was doing. One cop orders him across the street, which he did.

They eventually arrested him across the street.

Another videographer captured the scene, showing him clearly complying with the cops’ orders.

The incident apparently took place Thursday during a raid of an encampment in front of city hall where 12 people were arrested.
