We are still recovering from the horrible event in Las Vegas. Although little is known about the motive behind the killing, the U.S. is moving on and remembering those who lost their lives. But how do we prevent these mass shootings? First, we can tighten gun control so it is harder for murderers to aquire guns. Second, we can effective evacuation plans and tighter security so in case of an emergency, everyone can safely evacuate before anybody gets hurt. Last but not least, we could allow people to have more weapons so they can protect themselves. All of these actions have drawbacks, but hopefully in the future we can find an effective solution.
