Having a forged license is probably a more serious offense than driving without a license in Texas, and I'll bet in most other states as well. Some illegals in the Northeast US do it too, some that I know. I doubt she used it for actual driving. The pigs - oh I'm sorry, a slip of the tongue - the police should never have been called. The admission and billing person or persons at the clinic should have pointed out that they believed the license was invalid, warned her against using it, and then continued her through her checkup. That would have been the decent thing to do. But one has to remember in what State this occurred. I have no way to know what race, ethnicity, or world view the people at the desk were or had, but their response to the matter was a nasty, bone-headed move, and probably grounded in knee jerk, inbred racism.
However the lady's civil rights lawyers and/or illegal immigrant advocates pursue this case, they are going to loose, because the woman was most likely cited for using a forged document. The marching the lady off in handcuffs is par for the course, as an unnecessary procedure and a total overreaction. Screw the Texas police, Texan politicians, and the overlords that run that wretched state.
