well everyone has their reasons! but these people( cops and army who are beating all thosepeople), basically fall into three categories: 1. Just following orders without thinking what the consequences are.( or afraid of their superiors if they don't follow the orders). 2. Enjoy the power given to them all of a sudden , and afraid that if everything goes back to being normal, they'd lose this power. 3. are true royalists and therefore ignorant of what is going on and don't care about popular sentiments.
