My point is that it is not important what tool the killer used because anything could be used to do the same damage or more. What needs to be done is target protection and even that would be as difficult as removing all guns from existence. Until we can get every human in the world to stop killing other humans no amount of gun control laws will protect us. People need to be able to protect themselves and others because the police simply can't do it. The average response time for police here in my small town is 20 minutes and a lot can happen in those 20 minutes so one would need to be able to survive for those 20 minutes. Some places the response time can be over an hour and from what I hear some parts of New York city police never even respond to at all.
