First of all its nice to see people in other countries concerned. Second I am an elementary school teacher in the US. I also own several guns. That said, we do need more gun control. No citizen needs assault rifles. They are designed for killing people and nothing else. Would banning them stop mass murders? Probably not. People who are mentally broken will still kill with whatever means they can. I believe a solution could be gun control but not without a boost in mental health care. I can't leave this without saying one more thing. Humans can create the most wonderful, beautiful, amazing things, but they also do the most horrible, unthinkable evils every day.
