Laws are arbitrary rules. They do not dispense justice. He broke the law. Fining him is unjust.

Laws do not "dispense" anything. A fine is lawful; justice is an abstraction, like goodness. We live by laws, not by abstractions. Laws are indeed "arbitrary" rules, determined by elected representatives after discussion, in which abstractions like justice play a role.

It is arbitrariness in the enforcement of laws which may be unjust. I think that these detection methods are GREAT. Hope they put one at every intersection and catch every drunk and/or stupid driver.
