Excerpts:

"The limit on creating a registry applies only to the Attorney General (and thus to entities under his direct control, such as the Bureau of Alcohol, Tobacco, Firearms, and Explosives). By a straightforward application of inclusio unius exclusio alterius it is permissible for entities other than the Attorney General to create gun registries, using whatever information they can acquire from their own operations."

"So now let’s suppose that the Pennsylvanian is going to Maine. On the way, he travels through Massachusetts. Under current law, FOPA protects him. Under Manchin-Toomey, Massachusetts can arrest and imprison him, and he will have no federal defense. In Massachusetts, possession of a firearm without a state permit is punishable by imprisonment up to to 2 years."

"The result of the disparity is “pro-gun” provisions which are actually very strong anti-gun provisions: The supposed ban on federal firearms registration authorizes federal gun registration. The supposed strengthening of FOPA’s interstate transportation protection exempts two of the worst states (the reason why FOPA was needed in the first place), and provides any easy path for every other abusive state to make FOPA inapplicable."


My view is that when Chuck Schumer signs on to it, then it is not at all good for gun owners. Don't take the defeatist view that we need to compromise, that's baloney, if we stay strong we can defeat all new gun laws.
