It's not just me that's confused.  I heard one TV show where the reporter said the rioters were disgruntled immigrants,    and another TV show where the reporter said that the rioters were disgruntled right-wing ethnic Swedes who don't like immigrants.   Maybe they are both right ?  Are they fighting each other,  or both fighting the police ?   It seems to me to be counter-productive to be obfuscating this information because of some mis-conceived correctness.
