"In the domain of cops and robbers, an interdiction serves to structure a black market and a shadow economy"

This quote by William Irwin Thompson is referring to the power dynamics between law enforcement and wrongdoers. An interdiction is a legal term for a restriction or restriction, and in this context it is describing the laws and policies that are put in location by law enforcement to avoid criminal activity. Nevertheless, these laws and regulations can also have the unexpected effect of developing a black market and a shadow economy. This is because when specific activities are forbidden, it develops a reward for crooks to discover methods to prevent the law and engage in these activities illegally. This creates a black market and a shadow economy, which are both concealed from the law and run outside of the legal system. This quote is highlighting the complex relationship in between law enforcement and bad guys, and how laws and guidelines can have unintended repercussions.
