According to the Employment Minister of France, polygamy is one of the causes of the riots in France. This is the whole of the AFP dispatch (via Little Green Footballs):
"Polygamy among immigrants is one cause of the rioting that has plagued France for the past two weeks, according to Gerard Larcher, the Employment Minister.
M Larcher was quoted as saying that large, polygamous families sometimes led to antisocial behaviour by youths who did not have a father figure in the home, making employers more cautious of hiring staff from ethnic minorities.
There are fears that M Larcher’s comments could further fuel the debate about the cause of the unrest and possibly outrage Muslim and anti-racism groups. Polygamy is banned in France, but an estimated 30,000 mainly African families have more than one wife.
The National Assembly yesterday approved a three-month extension to the state of emergency."
