Dreadful. It may be a while before we know what lies behind it although the express may have some information as it reminds us that Islamic State have been behind several killings in Europe
What are the right on liberal left doing or not doing in Sweden (and maybe you mean elsewhere in Europe/the world), YMB? Are there a simple measures they should take that would stop shootings and other violence?
The firing was reported to have been directed at a particular car passing along the street. I must have missed the fatwa against that make and model......unless this is in fact a gangland event that has no connections with Islam. Mind you, in the eyes of some everything bad in the past, present and future now has a very simple explanation behind it. But the OP sentiment is correct, violence is likely never going to stop altogether.
