Clarification: You don’t need a permit to demonstrate in Sweden. They can still go and burn the Koran if they want to. Not getting a permit just means the police won’t help you out with diverting traffic etc etc. Police will only give permit if they can guarantee public order, and following recent events they don’t think they can for this demonstration. That in itself can be seen as a failure, but they’re still free to demonstrate, the police just won’t help them.
