These petitions come up every few months. They don't even gather a big enough number of signatures to get a reply.
For this to even have enough steam to gather the signatures (which they won't, and which will accomplish little), we'd need to have several big gun/conservative/libertarian bloggers to post it on their blogs (think Instapundit or something, but not just him - a dozen or two of the big bloggers doing it at once) - and then maybe it'll get 100,000 signatures.
