Under Represented?

We seek representation congruent to the size and scale of the inflicted wrong, however, how certain are we that we've rightly assessed the value of the thing wrong had been inflicted upon, let alone rightly assessed the charges? A scratch on a vehicle should demand the same punishment regardless of who it is who did it because the law of "do not scratch others" applies equally to all, regardless of who or what vehicle it was, the violation of the law still distinguishes the guilty party a "vehicle scratcher." What if you demanded more payment from a rich person who scratched an exotic sports car than from a poor person who scratched an old beat up Prius? Would you be a righteous judge?
