The Second Amendment is necessary for a free people to defend themselves from a tyrannical federal government.

In 1794, George Washington imposed a whiskey tax on the people of Pennsylvania. The people of Pennsylvania were infuriated and refused to pay the tax, so Alexander Hamilton sent nearly 14,000 federal troops to extinguish the rebellion and exert the new power of the federal government for tax collecting. This is an example of federal government abuse over the states. You also have to keep in mind that the states considered themselves to be their own countries at that time, so invading them with federal troops was tyrannical.

As far as the need for a federal ban on hand guns goes, it is unconstitutional because of the 10th Amendment, which Thomas Jefferson said is the most important, and that is: “The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively or to the people.”
