Dave Hardy, author of the excellent Of Arms and the Law, has a post where he discusses false flag gun groups.
What are false flag gun groups? These are organizations that are supposedly lobbying for gun rights, but which are in actuality arguing in favor of "reasonable gun laws". This helps advance the agenda of those who support the abolition of all privately owned firearms because every restriction is just something to be built on at a later time.
But the anti-gun lobby sometimes works out in the open. This article, also courtesy of Mr. Hardy, outlines some of their rather odd tactics.
