The speculation we are being overrun with illegal alien crime the statistics don't match the claim. Further to understand the nature of illegal immigration here in Arizona one need understand the nature of the labor market here. First Arizona's Agriculture business has long needed and used illegal alien labor as well as the home building industry here, along with many other industries too numerous to name. While it might get one votes or gin up the base to say you don't like illegal immigration the fact remains that most of the low cost labor that Arizona has been used to for a long long time now has been immigrants coming across the border. As of 2010 there was an est 460000 illegal immigrants in Arizona and that number is dropping due to the current economic climate here.
As for SB1070 itself the law does not really matter much in terms of what it will or won't do because in the end it won't do much other than hurt the taxpayers here in the state of Arizona.
