What is not said is that the proposal , said to be offered by the Brady Campaigne, if true, comes from a source that hardly owns enough politicians to insure any outcome. And the Brady Campaigne has long wanted to ban at least as much as the latest beware email suggests. The NRA owns more politians than Brady, even though they probably ran more than a few off with political rants and side taking in elections over recent years.
I haven't looked at the NRA site but I got a feeling they might put their two cents in....along with a request to send them some money.
Now I'm starting to get that paranoid feeling....from more sides than one.

Edit:
Just went to the NRA site. Looks like the new plan is really not all that new and here is this quote as to a legislative offering:
This legislation was proposed in February of 2007. Nothing became of it.
Current Efforts to Ban “Assault Weapons”
H.R. 1022, introduced by Rep. Carolyn McCarthy (D-N.Y.), would ban every gun banned in 1994, plus guns made to comply with the ban; guns exempted by the ban; fixed-magazine, semi-automatic, center-fire rifles holding more than 10 rounds; semi-automatic shotguns; detachable-magazine semi-automatic rifles; and any semi-automatic shotgun or rifle an Attorney General one day claims isn’t “sporting.”......
