Adam Kokesh, an Iraq War veteran turned antiwar activist, was handcuffed by undercover FBI agents after trying to photograph police making a traffic stop.

The incident occurred Tuesday when Kokesh and a friend were walking down the street and encountered an agitated police officer ordering another car to stop.

Kokesh pulled out his cell phone and snapped a few photos, but the cop jumped out of his car and grabbed Kokesh, spinning him around and putting his hands on the car.

Within minutes, a dozen cop cars and undercover FBI agents swarmed Kokesh, handcuffing him and ordering him to delete the photos, but Kokesh refused.

Finally, they released Kokesh without deleting his photos. For more details on this story, check out the video.
