THE power of regulating the militia, and of commanding its services in times of insurrection and invasion are natural incidents to the duties of superintending the common defense, and of watching over the internal peace of the Confederacy...Of the different grounds which have been taken in opposition to the plan of the convention, there is none that was so little to have been expected, or is so untenable in itself, as the one from which this particular provision has been attacked. If a well-regulated militia be the most natural defense of a free country, it ought certainly to be under the regulation and at the disposal of that body which is constituted the guardian of the national security. If standing armies are dangerous to liberty, an efficacious power over the militia, in the body to whose care the protection of the State is committed, ought, as far as possible, to take away the inducement and the pretext to such unfriendly institutions. If the federal government can command the aid of the militia in those emergencies which call for the military arm in support of the civil magistrate, it can the better dispense with the employment of a different kind of force. If it cannot avail itself of the former, it will be obliged to recur to the latter. To render an army unnecessary, will be a more certain method of preventing its existence than a thousand prohibitions upon paper.DO you still want to argue that well-regulated does not mean under strict control by laws?
This is yet another aspect where facts and history are against you if you want to try and argue that it means "well-trained".
