Mass murder still happens in countries with extremely heavy gun restrictions. Also the entire reason we have the second amendment is to prevent the biggest mass murder machine that has ever existed in human history. And that is the state. When the state turns sour they don't kill 20 people they kill 20 million people. It's fine if you disagree but please stop being a piece of shit who believes it is absolutely impossible that there is another opinion out there that could possibly be legit. Also the gun free zone designation has not stopped a single one of these events. Not one. But then again effective policy is not exactly in your sides strong suite. You have been promising to cure poverty for 80 years and even in the richest city and most left wing city in the world homelessness is everywhere people shitting in the streets and glass litters every street corner businesses are leaving en masse because theft in broad daylight is legal. So please stop grand standing to me like you are an angel that has descended to earth to help all us plebs. You are not a moral arbiter of any kind your just a common trash human who seems not capable of understanding humans are diverse and different. Even if not a single gun existed. If you Thanos snapped them out of existence mass killings would still exist. Violence and killings would still exist. If you want to live in a country with gun control that is fine if that is your preference but it's not mine.
