Yes...we should prepare for this to happen more often and closer to home.People ( especially young ) are helpless and angry , they can not channel this anger trough political process (practically no use of voting any more)so what is needed is just a small spark to start fire...
We read but it seems far away from our daily life, that some ( many people now) even in western world can't afford food, medicine, accommodation...so anger is building...They say that people should work and support themselves but Salvation Army here in Australia ( where things are not YET that bad) said that more and more working people can't afford food...
Not happy times in front all of us...
