You make serious allegations. You claim that those who administer the database are either incompetent or that they are purposely manipulating the data in order to show a problem where there is none.
Since fraud IS rampant in relation to immigration issues, a federal investigation has PROVEN that to be true, and the INS is the agency where much of that fraud has taken place, I'd say the only "problem" with the data is that it is in fact valid. Perhaps someone should look into that company you used as an example a little closer, if you know what I mean...
