They seem to be quite normal for their age and lack of maturity. Added to that they have been sheltered and forced to follow diktats that have resulted in making them repressed and frustrated. It seems that no-one in the community is prepared to explore this angle and whether the community/culture has some responsibility for such outcomes. I have seen such outcomes (and worse) for decades but things have not really moved that much.
You have to be careful what you believe of the MSM. Some of these protests are orchestrated as a divide and rule policy by govt officials themselves. It has a two-pronged effect, divides the communities and serves to punish those who were really involved in violence and thuggery. Many such events are regularly exposed on alternative media.
