Changing gun laws won't change anything except for punishing law-abiding citizens who already obey the gun laws we have.
What the government needs to do is follow through with capital punishment for those who are convicted of first-degree murder whether it be via a gun or another means.
There should not be a sentence of life in prison for a convicted murderer; it should be an automatic death sentence unless the person is proven to be mentally ill.
It is wrong for tax-paying citizens to keep these so-called human beings for a life in prison. Just like the people on death row. Most of them die of old age waiting and living on our tax dollars. Put them to death in the same manner that their victim was put to death.
This just might make a person think twice about killing someone knowing he/she will be put to death the same way.
