I saw this gun control meme the other day. We shall call it the “kid on the playground” argument. It’s meant to be a rebuttal of the gun rights argument, “Only a good guy with a gun can stop a bad guy with a gun.” What do you think? Is it a valid rebuttal?
The “kid on the playground argument” is an argument from analogy, comparing one situation to another. But it fails in a number of ways. An argument from analogy is only effective if the two things being compared are similar in their most essential points. But this is not the case with the “kid on the playground” argument and the “good guy with a gun” argument.
First, a kid on the playground throwing rocks is not very similar to a man firing a gun in terms of their effects. We’re comparing cuts and bruises to lethal wounds. This is a fatal flaw in the analogy.
But there is more. In the “good guy with a gun” argument, there is no one analogous to the teacher in the “kid on the playground” argument. There is no one who gives guns to all the good guys. Good guys choose for themselves whether or not to acquire/carry/use a gun (that is, where good guys are not prohibited by law from doing so).
The “kid on the playground argument” also fails because the assertion that “only a good kid with a rock can stop a bad kid with a rock” is false, whereas the assertion that “only a good guy with a gun can stop a bad guy with a gun” is (for the most part) true. Would it not be possible for another kid or group of kids or a teacher to physically restrain the bad kid with a rock with very little risk of injury? But the risk is tremendously high for an unarmed man or group of men to attempt to physically restrain a man with a gun.
The “kid on the playground argument” is thus shown to be a false analogy.
But the argument fails in another way, too. Even though good kids armed with rocks are not the only way to stop a bad kid armed with a rock, it is nevertheless one way to do so. Whether the good kids got their rocks from a teacher or acquired them for themselves, the bad kid would think twice before throwing his rock if he knew there were dozens of other kids on the playground who might pelt him back. Bullies thrive when their victims have no means to defend themselves. So do criminals. And both bullies and criminals are deterred when they know their potential victims are armed with equal or superior force.
