There are two types of people who conduct these sort of violent behavior to another human being, the one who plan everything and the other part is that the people who can get brain washed easily, from my understanding everything depends upon money, they are getting enough funds to create these sort of unrest activities around the world and they have the skills to brain wash individuals who have extreme thinking and majority of them are in the age group of 12 to 25. My conclusion is, it is all about money.
