When participants in a peaceful, non-violent march which departed from the Freedom Square Occupy Washington DC staging area attempted to enter the National Air and Space Museum, guards and police responded violently, throwing people to the ground, pepper-spraying a journalist and protesters so the doors outside were surrounded by people choking, wheezing, prostrated on the ground, eyes blinded or tearing from direct and indirect exposure to pepper spray. 

I had gone ahead of the group of 700-1500 protesters, carrying signs opposing the use of drones to indiscriminately kill. The National Air and Space Museum had been targeted because it is celebrating the use of drones. 

After less than a dozen people had entered the foyer of the museum, and just a handful of activists had entered the actual museum, guards rushed to the doors and blocked further entry. 

Within seconds, more guards arrived. They started spraying pepper spray at anyone nearby.

It happened so fast it's hard to sort out what exactly happened. But we know that at least one photojournalist, Cheryl Biren, who took the above and following photo, with clearly displayed media /Press ID was sprayed directly.

The guards pursued people outside, continuing to pepper-spray people indiscriminately.

Following the interaction between the guards and the protesters and media people, a member of the police SWAT team came out, cleared people from the door, announcing that the museum was "shut down."
