There are so many laws on the book that at any given moment you are breaking one without even realizing it. They are designed to make everyone a criminal, so that the police can arrest you for any cause. Do you know how many arrests have been made on because of a broken tail light? The broken tail light is the number one reason police use to pull someone over, and because they pull you over, they have to inspect and search you vehicle, and if they find some other infraction on you they can make a charges stick because the broken tail light gave the police probably cause to stop you to begin with.
When there are so many laws in the book, the police can use any one of them as tools not for serving the people but by selectively using them to control the people. This is similar to the how public institutions used to discriminate, they set up arbitrary admissions tests that would just happen to be that much more difficult for “undesirables.”
Here is commentary on admissions question that were used on Jewish applications. As described by the comments, the problem set given Jewish applicants were just that more difficult to answer and any mistaken would disqualify you. This is what happens when you have complex set of rules, laws, or ordinances. When you have a complex body of laws, the population may at time be trespassing any one of those laws but since they are enforced selectively.
Do you really believe, even today, that all laws are enforced equally? I’ve never seen a jay walking ticket be given out in an affluent neighborhood, even though kids take up a whole block to toss the ball around.
