By mid-Heian, the Guard was merely ceremonial, an office with no real duties for nobles of rank. But they had snazzy uniforms! This poem shows the contempt the nobles had for the lower classes, viewing them as nearly sub-human (please note that I do not hold these views, but my persona would have been expected to). Crime was rampant in the capital, in large part due to the fact that those ostensibly responsible for law enforcement were doing little more than going through the motions. It strikes me as having certain parallels to what is happening with the Occupy movement. The Heian nobles made up less than 1% of the population, yet the wealth gap was even greater than in modern America. The modern police force is being used to oust the protestors, while ignoring real crime; there are accounts of police not arriving to investigate crimes such as home invasions until hours afterwards, because the entire force was engaged in actions such as fracturing the skulls of veterans.
