Christine Neumann-Ortiz, disagrees. “I think the enforcement-only approach is a failure,” she says. She is director of Milwaukee’s Voces de la Frontera, which leads an annual immigration march through the city. She says that violent criminals should be removed, but that cracking down on those who are simply trying to make a living drives them further underground.Since Ms. Neumann-Ortiz doesn't seem to think identity theft is very serious offense, I suggest that she allow an illegal alien to use her social security number. I would if her attitude would change once she had to deal with the tax, credit, and possible criminal consequences.
