The advancement of weapons have cause positive and negative progress in the entire world. Weapons were created to protect, therefore this is the main use of weapons. we now rely on weapons to protect the entire world. if someone was to attack our homes we have the ability to defend ourselves with weapons. yet, weapons cause death and i believe it will lead to the eventual downfall of society. mostly anyone can get their hands on weapons. we can control the sale of weapons but we do not have the ability to control peoples minds. the consumer may use any weapon as they desire.... the advancement of any weapon causes more dependability in a weapon and more death from it as well.
