Dealing with the US constitution only, a study can be done while taking into consideration how it was written in a time when slavery was completely acceptable. And so keeping that in mind, it can be amended greatly now in order to make it suitable guidelines for modern society.
My analysis would begin with gun control lacking in the US constitution and ways to update it to make it applicable to the modern world.
However, having said that, I have no ambitions to do so when the rest of the world is benefitting from the slaughter. If ASD..... asks, I'll provide an explanation of how the world benefits.
And I'll leave it at that for now so we can enjoy the counter-arguments and foaming at the mouth from the kiddiespammer.
