Why Every Individual On This Planet Should Keep and Bear Weapons

While this was taken off a tragic situation currently developing in a war-torn region, the point being made here is:

Mentally screwed people who kill unarmed, defenseless people do exist in this world, always has been, and always will be. Innocence is not an insurance against your right to life and property forcibly taken away from you.

The brainwashing that one should not defend oneself / resist (when one's right to property and life is threatened) up to and including deadly force runs deep in most parts of the world.

This has to change. The right to resist with force including deadly force to neutralize a threat to your individual rights and liberties is a Natural Law right for every individual, whether he/she is aware of it or not.
