Obama just gave many of them amnesty and very few states are interested in kicking them out. The ones that are are being stonewalled by homeland Security.
So I’d say their Pigmentation immunity is working fairly well.
You make it seem like they are getting away with something. They in fact are only delaying the inevitable. In the normal course of things this is going to take awhile to litigate in civil court to get the docs and then the indict in criminal court for any criminal actions.
The criminal component will take place after a new POTUS and new US AG are installed in January. Eric Holder and others will be prosecuted at minimum for lying to Congress (Roger Clemens?) and committing a conspiracy to cover-up criminal acts undertaken by our government. Of course there could be more severe indictments if Holder actually authorized F&F.
