Many people have that thought. I think that assessment may be erroneous. I have worked in El Paso, Sierra Vista, Yuma, etc. What I have found is two things (1) law enforcement is alive and well in these areas, (2) the people coming across the border are not looking to do activities that get them arrested near the boarder. I feel significantly safer walking the streets of Nogales, AZ or El Paso, TX day or night, than I would walking the streets of Chicago or in many parts of the Bay area. In fact, I have zero issues walking in downtown El Paso at 2am on a Saturday morning. I can't say that for Chicago or San Francisco.
