Same as drug dealers, bookies, pimps, and white collar criminals, if you’re earning an income by breaking the law, then all of your assets are considered ill-gotten gain and subject to criminal forfeiture.
If any one of the States passed a criminal asset forfeiture law for any illegal immigrant, it would strongly disincentive an immigrant to come here illegally, and the illegal population would plummet overnight.
If an illegal immigrant gets pulled over at a traffic stop, the local police can impound his car; just like they’d do to a drug dealer. Then go to his house and take all of his shit. Local law enforcement can fund their efforts by auctioning the houses, cars, flat screens and any other assets in the possession of someone working here illegally. Thus the beauty of this law is that it wouldn’t cost anything. We wouldn’t have to worry about deportation hearings, and detainment, and transportation out of the country. We simply remove the economic incentive to come here illegally. Let the municipal police and county sheriffs handle illegal immigration and give them an incentive, which is keeping the proceeds from the asset auctions.
