&gt;ANY powers not mentioned explicitly in the Constitution are supposed to be reserved for the people.<p>Of course, but that only applies if the government is still good.<p>Should a situation arise where the government decides to become evil, then the government will not give a f*ck about the people&#x27;s reserved rights.<p>At that point, it will become hard to fight the government, if the people have no guns and especially hard if the people no standing well-regulated militia groups of men to enforce and defend the reserved rights of the people.<p>This is why the founding fathers want to guarantee the peoples the right to the standing of well-regulated militias groups.  Because if the peoples does not have well-regulated militia groups to defend them, then the government can just decide to become corrupt, and there will be nothing that the people can do.  By then, it&#x27;ll be too late to start recruiting, training, and buying guns and ammo.<p>However, if the people have well-regulated militia groups standing by, then the government will have to fight a bloody war against the people&#x27;s well-regulated militia groups first before the government can become a full fledged dictatorship.
