"the people of the United states who are peaceable citizens from keeping their own arms..."

ROTFLMAO.

It's simple arithmetic. Right now, far far more people in the USA are unlawfully killed by guns than are lawfully killed by guns.

Far far more people in the USA are killed by lawbreakers using guns as adjuncts to some other type of lawbreaking than are killed by "respectable citizens" using guns in self defence.

Moreover...

The rationale for the constitutional right to bear arms was the need to be able to raise a well-armed militia against foreign armies. The arms even in the USA in private hands are a broken reed in any military conflict in today's world.

The US is inanely attached to a period in history when as a result of a civil war a large part of the USA was a failed state where the writ of government did not run.

It is time to grow up and put away dangerous toys.
