You'd be surprised at how many people offer that inane argument as a reason for disarming people. After 9/11 when there was talk about arming pilots, I talked to more than a few people who laughed and said the criminals/terrorists would just take the guns away from the pilot. This after 9/11. Sure, a very likely military trained pilot will allow a bunch of terrorists to take his or her gun away away knowing that the terrorists, most likely Islamist fanatics, will crash the plane somewhere. Every account, naturally never printed in mainstream publications, of average citizens, especiallly females, using guns to defend him or herselves destroys the "they'll just take your gun away" stupid argument.
I managed to shut up one of the people I know who came up with that by saying he was welcome to come by my house and take my gun away if he could, and what time was he planning on doing this so I'd be sure to be home and have an EMT ready, but he didn't take me up on it. Nevertheless, I'm sure the jackass was braying the same tune to someone else later. Logic doesn't enter anti-gunner's pointy little heads. Gun control is a form of religion. For the true believer no proof is necessary, and no disproof possible (Stuart Chase)
