The argument that gun is useless because in a particular circumstance you might not be able to use it in time, or it might not save you, is no less nonsensical than the argument that there is no point owning or using a seat belt, since if you collide head on with a tractor trailer, it will not save you, and in some cases it might be better if you were thrown clear.
Similarly, the fact that “it might be used against you” is true of any tool, since the use of a tool depends on the purpose of the person wielding it. A recent syndicated column by Mike Royko pointed out, for example, that a number of murders in Chicago had been committed by drowning the victims in toilets. Ms. Jones could with equal force assert, “Bring a toilet into the home, and he might use it against you.”
