two questions

Hi Teacher,

I am not quite sure about the meanings of the following two sentences. Please give me a hand.

1. Further outcomes include the race riots which dominate the news with a
historical consistency that has involved virtually every non-White racial
group.

2. Cottle identifies the competing repertoires of preferred terms used by
journalists and their sources to define the contested realities of inner city
disorder.

Thanks a bunch.

The first says that there have been race riots involving every non-white group and there may/will be more.
Journalists use one term, presumably a more polite, more PC one, and the sources tend to use other tewrms, probably more colloquial.
