I think the concern is not so much a desire for arbitrary enforcement as it is a fear of perfect enforcement at all times. I think some degree of freedom is a fundamental need of the human being, even from the rules we set for ourselves. We don't actually want all of our laws to be perfectly enforced all of the time, for a lot of reasons. For one thing, the laws themselves are unlikely to ever be perfect, even if perfect enforcement leads to more scrutiny and tweaking.
perfect enforcement sounds like it could be a great way to combat racism and other bias a police officer might have. laws being enforced imperfectly creates a class divide since the upper class won't feel the impact of bad laws on their communities.
