Supreme Court and Identity Theft

Within the past week, news has surged that the US supreme court is hearing a case that involves an illegal immigrant. The case involves a man who worked for six years under a false name, green card, and social security number and than apparently unknowingly changed these and passed in different numbers. Well these numbers were that of a US citizen and thus this man was prosecuted. The controversy surrounds the theme of if a person did not intentionally steal ones identity than how can he be held responsible for such. In my person opinion it is tough for the courts to determine if a person knowingly or unknowingly stole a persons identity to use for their ability to work. Therefore each case should be thought of as the offender knowingly stole the persons identification for even if they didn't mean too, they still put themselves in a position where they had to. The bigger problem may be the idea that these immigrants need to falsify their identifications in order to work, but with regards to this case it cannot be a determinant. I think that the supreme court should and will rule in the lower courts decisions to incarcerate this man and even extending two years onto his sentence in what seems that increasing penalties will decrease the amount of these crimes committed. All in all this is an extremely relevant topic to society and there have been multi-million dollar illegal trades occuring around identity theft and the courts and the legal system need to find a way to cut down on this type of crime.
