Most of us out here in the deserts of California have been boycotting the Cal big cities for years. And from what the California LEOs tell me, they have been doing what the AZ new law says for years. If you are asked for identification by one of them and can't show any then you are held until it can be determined who you are. If, in this process, it is determined that you are an illegal alien you are then put in immigration hold until the ICE can pick you up. A lady that I knew that was British got nailed that way. Her visa elapsed, she had no drivers license (driving under the influence), wouldn't show them her passport or didn't have it with her, and her accent sounded very British (profiling). She got put on immigration hold by the sheriff and ICE picked her up. Got sent back to merry old England, much to the consternation of the guy she was about to marry.
