Firearms are designed and engineered to launch a projectile. Military weapons systems are designed for lethality, thus some of those projectiles contain an explosive charge or ability to fragment (e.g., grenade launchers, artillery rounds, and "smart" projectiles) to increase the radius of damage. These projectiles are highly specialized and strictly controlled.
Arms for the civilian market for target-shooting, hunting and self-defense, vary in design according to the desired purpose and purchaser's preference, whether it's optimum accuracy (which requires very consistent weight and dimensions of the cartridge components) or performance on game. The person operating or wielding the firearm makes the choice on what the intended target may be. The firearm is a tool, which is a bit difficult for the metropolitan or urban dweller to absorb, since they are distanced from rural realities.
I readily recognize that we live in a more violent society, and I have my own supportable theories on that, but I've been a shooter for 50+ years and have used firearms responsibly in that time. I am a U.S. Marine veteran, I have a permit carry a concealed weapon, obtained after a national agency check and classroom instruction, and I carry discreetly to protect myself and others. I will not relinquish that right voluntarily.
I'm also licensed to drive an automobile and not a day goes by that I don't witness some fool texting while driving, in obvious violation of the law and "common sense" (however that may currently be defined).
It is a poor interpretation of justice to penalize those who conduct themselves responsibly and properly for the misdeeds of those who violate the laws of God and man.
Within my social outreach, those that scream the loudest for "gun control" seem to have allowed the television to babysit their children, apparently oblivious to the 1500-1800 homicides these children witness on network television in a year. Or they buy computers for their offspring's education, only to realize the kids are playing computer games that simulate and reward violence and bloodshed. Want to reduce violence with firearms? Promptly address antisocial behavior, animal abuse and bullying. Let's focus on responsible parenting instead of putting kids on autopilot for unsupervised play. If your head is screwed on tightly, teach your thought processes and behavioral standards to your children and model your high standards and polished judgment for them.
