Just because they have a suspended sentence does mean you can "do what you want", as the OP proclaims. The implications of being found guilty of a crime in a court of law will be potentially profound (background check, anyone?). I think the judge got it right, TBH. There is no evidence that their intent was anything other than protest. If they had planned to go and damage planes, vehicles, etc it would be another matter. Yes they were foolish and careless. They are now convicted criminals with a suspended jail term. I think that's enough. If I wanted more, I'd move to Saudi.
