flashes of the kind of city we should be working towards
The reality of urban riots is that they have always turned out to be the opposite of a learning experience for a city. Riots have nearly always resulted in politicians simplifying the problem even more, and looking away even further. After a riot your average city will become more afraid, more authoritarian, more segregated, more exclusive and less tolerant. That is the real tragedy of the post-war western urban riot, first it shocks and terrifies us, then for a moment it makes us see flashes of the kind of city we should be working towards, which then fades away into the darkness.
