Dominic Cummings is predicting riots in the UK, should a second referendum take place and the Remain vote prevail.
It is interesting to note that usually riots are the last resort of minorities, not majorities. More to follow on riots, the "silent minority" of brexiters and Dominic Cummings shortly, in this space.
Wikipedia lists the following classes of riots:
Police riot
Prison riot
Race riot
Religious riot
Student riots
Urban riots
Sports riots
Food and bread riots
From the list above it becomes apparent that Cummings' proposed or anticipated riots fit under no existing category since the anticipated perpetrators are the majority.
