Perhaps the best way to make this argument is by looking
at the immediate cause of the riots and at the locations in which the bulk of the
rioting took place.

The immediate cause of the riots was,
of course, the police shooting of Mark Duggan.  Duggan was from a lower-class
background.  The fact that the shooting of such a person was the immediate cause of the
riots implies that the distinctions between classes and the treatment of the lower
classes was a major factor in the riots.  In addition, the fact that much of the rioting
took place in relatively poor areas such as Brixton can be used to infer that it was
mainly lower class people who participated in the
rioting.

So, to argue that inequality caused the riots, you
can point to the immediate cause of the riots and the location of much of the
rioting.
