The only way to deal with the Mestizos if they are already in the US:   Round them up   Detain them temporarily at an ICE facility   Subject them to a mandatory caning or whipping   Tattoo them in a conspicuous place on their body so that it will be obvious to anyone if they sneak back in that they were once deported   Confiscate all monies they may have, seizing any property of value and auctioning it off   Take them to the Mexican border   Make unarmed and unescorted Mexican officials walk over the border to claim them and walk them back over. Do not release them into their custody until expenses for the cost of the deportation/investigation has been paid in full   That being said unwed or not, pregnant or not, barefoot or not I could not care less about the plight of anyone who broke the law to enter America and work illegally.
