Every country has mentally ill people, psychos, misogynists, and wannabe serial killers. But they don't get to carry out their violent plans because they don't have access to the most deadly weapons. I really, really get why the Second Amendment is so important in the U.S., I really do, and I support that reason for having guns; but I'm sorry America, it's time that you admit you have a gun and violence problem. It's true that there are always extenuating circumstances, and that guns don't kill people, people do. But guns make murder attempts exponentially more likely to succeed.
American culture is saturated in guns being the solution to whatever ails a person. In the movies, whenever shit gets real, the main character always just happens to have a gun. These shooting sprees at schools... I blame the media. They always sensationalize the killer. The victims get 5 minutes of air time before they dive into the deep psychology of some twisted asshole who was upset because he couldn't get laid.
Stop televising this shit with 24/7 coverage, and start making people lock up their guns in more secure arrangements.
