And let's be fair, it's not uncommon especially at larger protests for their to be conflict that requires police intervention. Just like how police forces will have the bad people that bring down the rest of the force, groups of protestors also face similar problems. Different people in the protest have different perspectives and ideas of what makes a good protest and what is effective. Some people think violence and destruction is needed and often these people have mob-like effect. If one person starts doing it often that spreads through the group and more people are breaking laws. Without some law and order in there things get out of hand pretty quick as we have seen in many protests in America, but also across the world.
