The essence of a dictatorship or ruling oligarchy reigning under color of law: The law applies when and how they decide. All citizens are in violation of something and the law is used as an instrumentality of control over those they target or protect those they favor.
Reminds me of an old movie, El Patrullero, about the corruption in the Mexican highway patrol.
The following clip (1:32) is in Spanish (sorry, I couldn’t find it with Enlgish subtitles). Basically the cadets are being questioned about the proper procedures during a traffic stop. The cadet responds that first you look for a moving violation, then for mechanical problems.....The commander then interrupts and says, “No, there is always a violation; first you arrest, then you search for the violation.”
The subject is certainly guilty, you just need to determine the extent of his guilt.
