The legality of the event is know. It was illegal, as deemed by a court of law. The question I was after is if the concept is ever moral or reasonable to deal with protestors with methods outside the legal system. Common methods are the military, but also martial law, suspending bank accounts (without a court decision), and other methods. Current in Sweden we had recent several demonstrations that lead to riots, and historically we had major ones including one that lead to several demonstrators getting shot. Every single time, researchers and government investigations has found that using anything other than the regular legal system is counter productive, and in some cases very deadly. If the police don't do their job you get more police from other regions. In a event just a few months ago, they even got police from nearby countries to help (despite massive demonstrations and influx of tourists, crime went significant down during that period). In general, the problem of police not doing their job seems to stem from when they are afraid. Either because of being extremely outnumbered, or in combination with poor instruction (with can lead to being afraid of doing mistakes in a political hot situation). Both are problems that can be solved by politicians without going outside the framework of the legal system.
