Like the other child comments I don’t agree with the presupposition that guns are an entity that somehow incites people to commit violent (Which is what you are implying).

For example most people have access to cars, statistically much more dangerous than guns, and no one seems to imply that having a car around incites people to violence. People who are mentally ill and dangerous could as easily use any array of common tools or methods to commit acts which are dangerous to themselves and others. That doesn’t make it the tool’s fault.
