It’s a threat that will become very real for those covering the street protests expected this weekend at the NATO summit in Chicago.

Just ask Carlos Miller. The photojournalist has been arrested three times. His “crime?” Attempting to photograph police actions in the U.S. Most recently, in January, Miller was filming the eviction of Occupy Wall Street activists from a park in downtown Miami.

In twist that’s become too familiar to many, the journalist became the story as police focused their crackdown on the scrum of reporters there to cover the eviction. Miller came face to face with Officer Nancy Perez, who confiscated his camera and placed him under arrest.

And Miller is not alone. Since Occupy Wall Street began last September, more than 75 journalists have been arrested.  My colleague Josh Stearns has chronicled these arrests since the movement’s earliest days. Stearns expects to see an uptick in arrests as thousands of protesters and reporters converge on Chicago.

Radical Transparency and the Police

Journalists record many of these arrests themselves as they’re shoved to the ground, shackled and hauled off to jail. Onlookers have documented many of these arrests as well.
