Probably b/c the clan has multiple identities boutght for several thousand dollars each from itinerant documents forgers......and are riding the US gravy train for plenty.....and ALL of the "dreamers" are voting illegally under each identity.
So, by Ohaha forcing them to get licenses under their real names, state computers will run a photo-match check to see if the same person has applied under different names.
Voila, they get investigated for ID theft and have to answer to a judge---and get prosecuted under US law. This frequently happens when a former illegal gets legal.
