Strange story, why would the police check him during the preflight check?
As mentioned in the original article, he had not begun anything. As a matter of fact, he only stepped out of the plane because the police, who was evidently conducting random preventative checks, told him to.
To those saying that the Swedish justice system was wrong in not convicting him, do you also advocate people being convicted just for being members of a particular political party (let's say the German NPD, f.e.)?
