Such a terrible thing to happen, and I wish my condolences to all involved. Hmm gun laws where do you strart and where do you stop? I guess we could also look at, Knifes laws Car laws Alcohol laws Drug laws And on and on I could go. How do you protect a community from every single unknown nut job that has finally decided that today is the day? How is this possible? What laws would need to be introduced? Not that many yrs ago there was no where the numbers of these incidences, yet the gun laws were no different then, perhaps the reasons behind this should be looked at. The world community as a whole has chaged, for the worse I believe. Teen suicide rates, linked to social media this yr worldwide i am sure would be a considerable number most not reported. Pressure on everyday people worldwide in their everyday lives is crazy at present. (WORLD ON EDGE) Our world leaders have alot to answer for. In saying all the above you will never remove or stop people from achieving such a crime that has happened today. Take all guns of everyone,? Hmm then the nutters will go a make a home made bomb. Where does it all stop? It won't, people intent, on conducting such crimes will always find a way to achieve their goals. All very sad the direction the world is heading.
