The weapons of violence 

can bring only the fruits of violence

Would we be surprised that we have so much violence? We have more guns per capita than other nation. More guns are packed into our land than anywhere else on earth.

A gun yields only one result. It yields violence. Nothing else. If you have the weapons of violence, of course you are going to have violence. Guns everywhere = violence everywhere.  It is said that, What you reap is what you sow. If you sow the gun, you will reap the harvest of the gun. And, the harvest of the gun is the hail of bullets.
