Correct, a most excellent explanation of the FOPA.

Now, as I understand Wikipedia, anyone may contribute. If a Brady-type writes a piece, on the same subject, that fails to mention any of the protective sections of the law, but only mentions those showing the Federal authority, which one will come up first when FOPA is searched in the search window?

If they alter the existing version, the Brady-FOPA would be the only one to show up from the search window - at least, that is, until it gets reverted for being PoV-heavy or biased.

If they write a new piece under a different name (such as "FOPA" or "Firearms Owner Protection Act of 1986"), instead, the current article would be pulled up instead.
