The Constitution says we have the right to bear arms, and it does not say that we can't have more than one for each arm. We should be able to have them piled up to our ceilings so we can roll in them and their beautiful black splendor. This is what many gun lovers would want you to believe, but don't fall for it.
Guns are dangerous weapons designed to kill humans and animals.
If we keep mounds of them lying around, one of them is bound to go off sometime and shoot someone's eye out. There are many fine bills in effect right now that regulate gun sales and purchases. The Brady Bill, for example, mandates a five-day waiting period on gun sales to allow for background checks on the prospective buyer. This is a good way to slow gun purchases and spontaneous shootings, but does little to actually decrease the number of guns in circulation. To control this, their production must be regulated by the government.
