Christian Egyptians stand in a human chain to protect Muslims as they pray, on Jan. 25th http://yfrog.com/h02gvclj

It should be noted that during Christmas there were wide spread attacks on Coptic Christians in Egypt that were fueled by the government fear factory. Moderate Muslims were outraged and formed bands across Egypt to protect their Christian neighbors during their services, and these social networks (formed largely on Facebook) were the same networks that would later be used to start the protests.
