Alright so just to be the devils advocate I should say that friatider.se isn't a newspaper that many Swedes would say is trustworthy and I guess it's possible that they left something out. I don't think that's the case, however.
That said, I wouldn't be surprised if it's completely true, either. Tingsrätten, which is the lowest court, is all over the place in their sentencing and I wouldn't be astonished if it continued to Hovrätten and the he would be fine (except for the fact that he broke Knivlagen). Though if that didn't happen I would be surprised either.
I guess my point is that nothing surprises me anymore, everything is chaos, I didn't ask to be born in this insanity. Please make it stop...
