>>I hold little to no hope that any of these suggestions will be implemented nationally. They make entirely too much sense and don't pander to anti-gun zealots or their checkbooks.

>It doesn't make sense. For example, what constitutes an "explosive device"? And what constitutes a "grave threat"? If somebody is planning a shooting or bombing by putting together supplies, then they're already in violation of existing laws.

For purposes of this statute, “explosive device” means any explosive device of sufficient firepower to kill or maim a human being. The details would be wrtten into the code.

"Grave and imminent" are legal terms which have been used many times and also would require definition in the code.

If they're not putting together supplies, it's something else that hasn't yet culminated into any personal actions. So do we prosecute people for their thoughts?

See "hate" crime laws. No smiley because I'm not kidding.

<snip> Your question about banning propane due to the story you post dovetails the example in the soapbox I posted regarding Sudafed & NY's current restriction on Vicadin.
