Rather than trying to stop illegals Arizona should go after employers and renters. You may be subject to civil and criminal penalties for hiring undocumented immigrant workers. Civil penalties range from a minimum of $375 per unauthorized worker for a first offense up to a maximum of $1,600 per worker for a third or subsequent offense. If you are found to have engaged in a "pattern and practice" of hiring undocumented workers, then you can be fined up to $3,000 per employee and/or imprisoned for up to six months.

And make land loards pay as well.
