Seriously. It's harder to get guns now than it was 50 or 60 years ago, and back then we didn't have mass shootings like we do now.Its not the guns that cause mass shootings, it's the lawlessness, decadence and immorality that permeates our society, those are the facts that are not in dispute.
Gang violence needs to end, which means that the drug culture needs to end, and prison sentences need to keep violent criminals off the streets.
