A gun is a piece of artillery with high muzzle velocity and trajectory bullet. A gun is used to hunt and shoot the living, dead. Guns kill.
Where do these mass shootings originate?
In the mind. There is a chain reaction to every action. Pulling the trigger on a weapon is the final moment of an event.
Weapons at this time in history seem to be an experiment on the loss of American humanity. Or a simple case of wealth, politics and the NRA power. Where does the guilt lay in the slaughter of American citizens? Everywhere. Everyone. Leaders, voters, gun sellers, gun buyers.
