"I want to be very clear in calling upon the Egyptian authorities to refrain from any violence against peaceful protesters. The people of Egypt have rights that are universal. That includes the right to peaceful assembly and association, the right to free speech, and the ability to determine their own destiny. These are human rights. And the United States will stand up for them everywhere." ~~ President Barack Obama
Apparently this only applies to demonstrations in other countries.
RAC80, a sit-in isn't violent. Also, that cop went down that row nice and slowly and then went back again for seconds the same way.
The same scenario occurred here in Los Angeles on Thursday morning, with people blocking the street. However, the Los Angeles Police Department's officers did NOT resort to the use of pepper spray to arrest people, and were surprisingly gentle as they pulled them upright after zipcuffing them. In neither situation was violence offered to the police, but only in Los Angeles did the police NOT use pepper spray.
I watched the entire thing on tv that morning, so I know there wasn't anything "hidden" from view.
