When I hear about someone shooting up a movie theater, school, or an office building, I think what kind of person would give a gun to a mentally ill man without doing an extensive background check. 

People may think that the gun stores should not sell guns to the public anymore. They should do more a background checks and restrict mentally ill person from purchasing the gun.
 
It is not the government’s fault for someone waking up one day and thinking “I’m going to shoot up a school and kill a bunch of teachers and students today.” When you take away guns you set up a whole new black market with more crime and violence. You can’t stop somebody from getting something they really want.

You will also see overpopulation of animals, which can become an issue. Without hunters with guns, animals will increase their population and they will take over cities to find new habitats.
 
This can also be bad for country folks who live off in the wild and live off of meat that they hunt.  When people are cut off from towns/cities, they have no source of food than what they hunt. A great example is people in Alaska or people that live in the hills of Arkansas.

In addition to hunting, many parents use weapons as a self-defense weapon.  In this corrupt world many people brake into houses for belongings that they can sell like jewelry, electronics, money, and appliances.  People can defend their homes with their weapon if we do not have all the guns taken away.  This can keep the crime rate at a minimum.  People can also use them when the government takes over and threatens the citizens of the United States.

Taking away guns is taking away the citizens’ Second Amendment right. We, the people, will take action.
