Observation: the police line looks like it was made up of *over half* females. Look at their little "fighting stance", one palm outward and the other hand on their spray/useless batons (batons are retarded and don't work). Another observation: This crowd was kind of aimlessly milling around, yapping at the cops, doing nothing... **until some guy with balls of steel got on a loudspeaker and, like a battle of old, shouted "ON ME! ON MY COUNT!"** And what happened when he finished counting? The group attacked. Groups this large tend to behave as a singular organism. All you need is one powerful voice that can cut through all the babbling to direct them. Once a crowd reaches a certain size, group psychology takes over. Allegedly, the average intelligence of a grown adult in a massive crowd actually *drops* to that of a 7 year old child; this is one theory for why it is so easy to manipulate large crowds, because it's essentially children that you are manipulating.
