From the beginning of time there has always been structures in place to ensure that individuals within society work within the confines of moral and ethical mores. Throughout history there have been different structures and people who ensured that these morals, ethical codes, and societal rules were followed.
When the lines become blurred and these same mores and individuals that were created to protect the populace begin to victimize them the very fabric of society as a whole is weakened. Law and order is integral to any society. It is often used to demarcate the civilized from the uncivilized, but even within the animal kingdom there is law and order. For example, study the behavior of lions, bears, and gorillas. They all have an organized method for breeding, mating, and ensuring their survival during climatical changes.
Although, laws change based off of various factors these laws whether man made or not create order. Without the one you can not have the other. When there is no law, there can never be any order. Paralegals are not required to be licensed like attorneys and other professions, but are tasked with furthering the aims of the law. This can not be avoided by considering the role as one that is merely a job based career and not one that has the responsibility to uphold the the law.
