Not the real sin ofc, but the meter here is BAD, like it is trying for ballad meter and it can't even do that. So many full stresses that need to be awkwardly suppressed ("rice flails""grim Kurdish") so many unnecessary syllables ("five kilos"? "Ten pounds" is right there) and as for the rhymes...
The Spectator has seen fit to republish a 2012 poem by Rod Liddle dedicated to the Metropolitan Police. Count the racist stereotypes and then ponder: do no white British people commit crime in London?
