What is the amendment 2?

The purpose of amendment 2 to the Constitution is to protect the rights of a free People to defend themselves from the tyranny of government. The explicit intent of the second amendment is to allow every person to own military style weapons in order to secure for the citizenry the ability to rebel against government tyranny at a moment's notice. The British attempted to disarm the Americans and later, when conflict was anticipated, to seize their military style arms from an arsenal, and since the first act of a tyrannical government is to disarm the citizens, the Founders put this protection in to ensure that military style weapons were free to own and could be kept by every individual, without license or knowledge by the State and without infringement.
