So was the research only on illegals, or all immigrants in LA? Makes a difference. And "non-citizen heads of household" does not necessarily equate to "illegal-immigrant heads of household." Just sayin'.

But why does everyone focus on stopping them from coming across the border with fences and such? Why keep persuing the most expensive solution? Start putting employers in jail. Force them to dissolve their business when they're caught hiring illegals. Zero tolerance for hiring undocumented workers. Remove the motivation for them crossing the border: jobs. When someone hires an illegal, they're aiding and abetting a criminal. They should go to jail and lose their business since they've proven they can't run it legally.
