Nonsense!! If one cop did "confront" another cop, it was only because he believed he was getting screwed on his cut of the criminal action!
The Democraps are KILLING us with this at the polls. In LA, Obeso would be registered as OBESO." He would more than likely have a full set of papers including a DL and SS. He would also be registered as MONTOYA, with a DL and other ID to match. Of course a couple of Matriculas Consulares would round out the paperwork.
Where it really gets tricky? He could also be known as Montoya-Obeso, Obeso-Montoya, Montoya de Obeso, Obeso de Montoya, and if el jefe were particulary proud of Mom's family (probably but not certainly the Montoyas, he might borrow a couple of their handles as well.)
Bottom line? Not at all unusual for the same people to be collecting multiple benefits from the US in Mexico, in California, or TexaS. NOT ONLY DO WE HAVE NO IDEA ... NOT THE FOGGIEST .... HOW MANY MEXICANS WE HAVE, LEGAL AND ILLEGAL, WE HAVE NO REAL IDEA OF WHAT THEIR NAMES ARE!
In the infamous Dornan-Loretta Sanchez Congressional Election case, Obeso Montoya would have been good for a dozen Sanchez votes and not even necessarily know about it! (Although he might well have gone to his "normal" precinct and voted in person, too.
VIVA LA RAZA ...GRINGO!
