Exercising one's rights. A means to prevent tyranny. Self defense. The means to hunt.
Yes, of course they do. They give a feeling of safety and security. Would someone without a firearm go outside to their dead end road to confront a vehicle that had no business being there? Would you answer a knock on the door in the middle of the night without gun in hand? Would you drive into a bad neighborhood unarmed?
Do firearms empower people? Note that this is not pertaining specifically to the US or the 2nd amendment, but rather a general question.
But Im not asking about subject"feelings" here. Im asking about demonstrable differences in outcome.
