I think things will get violent. Certainly for a time when the penny drops with a proportion of the leavers that they didn't vote for what they thought the did. I can see civil unrest and racially motivated riots. Maybe even a resurgence of Brixton, Toxteth etc.
i still feel incredibly sad about this vote. Not least because I hoped the Britain of today was a generally peaceful and tolerant society that had genuinely begun to embrace a multicultural heritage.
Id hoped the racist and bigoted society I walked away from in the 1990's had made peace with change. But actually it's more hateful than ever. I've never been so ashamed to be British.
