Not that anyone needed a rule, but if you don't have a rule to break then you have to fall back on the Ten Commandments and God as a judge. It is so much better to have a government to establish the rules, bring offenders to justice and the PUNISH them, because any punishment from a vengeful God will be eternal... or so the reasoning goes.
Another point is that the judges, juries and lawyers can all be bought - they just cost so much more than an honest man, much. The nightly news covered the demonstrations promised by some extreme sect at a funeral, the same group protesting the honoring of the war dead. Now, if the news report - didn't have color video, reporters questioning, and NATION WIDE exposure - if they had just texted it on our screen for us to read in black and white? Would it, the protest, have been effective at all? The terrorists won the war against America with the crashing of four aircraft, and your federal government has lost track of 119,000 aircraft - which could be used for drug dealing or crashing into government buildings or hospitals or schools and since they haven't got that under control they are going to be much harder on none registered fliers and their aircraft soon. In Britian in WWII the cities were bombed and bombed and no one took a day off, they kept going, how soft civilization has become.
But remember, I will tell you that there are four rules of safety at my Appleseed, and if you fail to follow them there are consequences, could kill someone, but I won't hang you from a tree because you didn't get the first lesson, we will work with you to the point you get them and live by them for the weekend, or we will suggest that you sit and watch.
