Assuming we take the OP's story at face value (obviously something you wouldn't do in a courtroom!), surely there's enough evidence here for a case, even if the defendant isn't, at the end of the day, convicted? Or is Sweden more averse to questionable cases than the US? At least according to this thesis [1], the difference in conviction rate between Sweden and the US doesn't seem to be large enough to support that idea.
