The article says that the corruption was isolated. A google search turns up a Debbie Schussel article (linked from Michelle Malkin’s site) that says these indictments were kept underwraps for about four years. It took four years to investigate an isolated case of corruption, or to determine that fact? I am not encouraged.
Ever notice how cockroaches scatter when you hit the light? I think - if other recent cases: Holy Land Foundation comes to mind are any indication - the feds have been using night vision on this case, watching this operation to gather intel on the contacts of these contacts etc. over the years. Lets hope.
I'd look to Steve Emersons or Robert Spencers sites for their takes.
