The federal government was never granted the power to “ensure domestic tranquillity”. Nice try though. Now what does it say to about you that you’re too shortsighted to realize this man could have crashed his plane into the crowd, killing 2,000 instead of 59 and that that is exactly what will happen if your idiotic desire to ban firearms was achieved? It’s sad that you literally can’t grasp that anything can be used to kill. Anything. And the only thing that will stop a person with a desire to kill is to incapacitate that person. The Spetsnaz teach that man is the only weapon in the world. Everything else is merely a tool. Your idiotic ramblings would end with the plane being the tool and more dead. And why? Because you insist on replacing logic and reason with emotion.
