Read the excerpt from Midsummer by Derek Walcott.
With the stampeding hiss and scurry of green lemmings,
midsummer's leaves race to extinction like the roar
of a Brixton riot tunneled by water hoses;
they seethe toward autumn's fire—it is in their nature,
being men as well as leaves, to die for the sun.
Based on the excerpt, what is the speaker's perspective on the riot?
