Yet somehow in actual tyrannical states it doesn't solve anything, and in states where there are more guns than population it mostly just costs the lives of childen and citizens who were going about their day.

Life also doesn't revolve around states and guns, and countries that do seem to have a partial culture revolving around just that are generally very young countries that seem to be stuck in a vicious circle.

Instead of blindly deferring reality to an amendment to a man-made rule you could also engage in proactive betterment of society.
