"Opponents of gun restrictions often argue that even seemingly modest restrictions are the first step towards total bans on all guns or all handguns.The whole document can be found here, I strongly urge you read it and bookmark it for later reference.
Some proponents of gun restrictions mock this: No-one is talking about gun bans, they say -- the slippery slope concern is groundless. In the words of Martin Dyckman, associate editor of the St. Petersburg Times (Dec. 12, 1993, at 3D), "no one is seriously proposing to ban or confiscate all guns. You hear that only from the gun lobby itself, which whistles up this bogeyman whenever some reasonable regulation is proposed."
Who is right here? Is it true that no-one is seriously proposing broad gun bans? Is it true that the slippery slope concern is just a bogeyman? Here are a few relevant quotes on this point. (All of them have been verified by me, Eugene Volokh, Professor of Law, UCLA Law School, with help from our excellent law library.)
1. Quotes from gun control proponents praising the slippery slope, and urging mild restrictions as steps toward a total ban.
2. Citations to laws that in fact ban all guns or all handguns.
3. Quotes from politicians urging gun bans.
4. Quotes from leading media figures and institutions urging gun bans.
5. Quotes from advocacy groups urging gun bans.
