Holy crap the Germans don't mess about eh....
I take that as sarcasm :)
Well, in recent years they have started to enforce rules a lot harsher than they used to. But, unfortunately, in a lot of cases they have deported the wrong people.
For example families from Kosovo and Bosnia which lived in Germany for over 15 years were suddenly deported. Sometimes the children were born in Germany, have never been to Kosovo and hardly speak the language of the country they are being deported to. There have been reports on immigrations surprising families with a visit at 4am, made them pack up their belongings and brought them straight to the airport without any notice. Three hours later they were in a country where they had no home anymore, no source of income and hardly anyone to go to. Even in Kosovo the 100 Euro assistance money to get "settled" doesn't go a long way.
Mostly these were families who tried everything to integrate in Germany, even spoke German at home so their children could get a decent education in a German school.
Then you have people, who before going to Germany to claim asylum already plan to break every rule possible and even ask about it on forums. Those are the ones who are most likely to get away with it, exploring every single loophole.
To be honest, it makes me sick......
