There was no appeal left for this man.  Sweden is not such a push-over country as you seem to think.  But finding people who do their best to hide is like looking for a needle in a
haystack.  The Swedish authorities are dealing with 10s of thousands of similar cases
where a person has been denied asylum, effectively telling them to get out.  But if the
person does its utmost to hide it's very difficult to find someone.  Sweden is not a police
state where every person is controlled by personal chips or gps systems.  It is a serious country who takes its UN membership seriously and adhere to the rules and regulations
about the process of asylum.  Unfortunately it's an imperfect system, but our liberal
societies are still better than the alternatives.  To most of us.
