There are many examples of the need to bear arms, not just from the American Revolution resulting in our Bill of Rights to protect us from a corrupt government, but you see people fighting corrupt governments all over the world. Austrailia may be one of the few countries that didn't have to fight for their freedoms and rights. I don't know what your government's like, but the odds of it not being corrupt are slim.
After they seize your money, it doesn't take long before they're controlling your every move in the name of "protection". We need to protect ourselves from them.
