"Are you sure we don't?" Harry retorted. "Just because you know a spell doesn't mean you're going to use it. Something you all may have missed is that everyone in the magical world is armed with a deadly weapon most of the time. In general, these people don't go on rampages."
"Something most people gloss over is the fact that the wizarding world is an armed society," Harry agreed. "Yesterday hundreds of people in the wizarding world went through their day without killing anyone. I'd say that most of these people knew spells that could cause harm or death and none of them used them."
"That's fine Luna," Harry said warmly. "If you took away their wands then they'd use knives, take away the knives they'd use sticks, take away the sticks they'd use rocks, take away the rocks they'd use their teeth, break out their teeth then they'd use their arms and legs . . ."
This is how I feel, people are the problem, as you know.... but guns are my hobby, an important hobby to me. And for your understanding Harry Potter lays it on the line.
