How can we stop shootings?

When thinking about what I was going to write for this blog I came across an article that describes a shooting that occurred killing five people. It makes me upset and angry that there really isnt any way to stop these shootings. I believe that there needs to be stricter laws prohibiting the purchase of some guns. There really isnt a way to stop people carrying guns around towns or cities because then we would have to search everyone, it needs to start with not allowing some people to purchase guns. When people are selling guns sometimes they dont realize it but they are really selling the gun to someone that is going to do a violent and stupid act. There needs to be some way that we can reduce the number of shootings every year.
