I still like the suggestion from earlier: 2005 Drunken yobs beating up other people because they can.  Ethnic is no good, because ethnic basically means non-anglo saxon, and mostly anglo's were involved here, even if there was a small number of non-whites as well.  Race riot pretty much covers what happened, one group attacking people because of their race.

The French riots weren't especially aimed at people.  Most of the damage was to property.  That was more about class, or underclass.  Here, the riots are not obviously about class, but race.  And in both countries, there were not a large number of migrants involved, the french rioters and westies being mostly 2nd generation and the surfies probably 3rd, 4th or 5th generation, at a rough guess.

As discussed earlier, there really has only been one real riot.  And as discussed earlier, the other titles, as with the current title in fact, cover a lot more territory than just the events of recent days.
