Missing Pro-Gun Petitions: Did They Get Yanked?

Matt, over at Freedom Is Mandatory, linked to a post about petitions for signing at the White House web site.

I read the post then jumped to the site to add my signature to each one.

Yeah, I know the original post was back in mid-October, but I figured better late than never, right?

Then I got the following message:
For all four petitions.

Did they really fail to meet the signature threshold?

Or did they get pulled from the site because they're pro-gun?

Seems kinda dodgy to me.

Anyone know what's the what here?

[UPDATE 11/7/11: Turns out the petitions really did fail to hit the target number. And honestly, I find that bothersome.]
