Law isn't code, and nor is a constitution, but it appears the point of the second amendment was to be a backstop against most of the things that could go wrong in such pernicious applications of the law, where if the people can revolt within the confines of the rules, you don't have to throw out the constitution and everything it built. If he found a rule that could be used to overwrite every other rule, there is the option to use popular revolt against the party who was abusing it. As they say, it's a republic, if you can keep it.
