A quote from Eduard Gnesa, director of the Swiss migration office, at Swiss Info, 14 February 2008

It's also possible under Swiss law to expel the [non-Swiss] parents of juvenile delinquents, for example, if they neglect their children or fail to comply with conditions set by the school authorities. […] We don't want ghettos or a two-class society like in Britain or suburbs like in France where [immigrant youth] set cars on fire.
