People who are convicted of particular offences in all the states in America have their DNA collected. There is a promotion by the law enforcers in relation with data banking of DNA, as there is a theory that it can help in clearing unsolved crimes which had been committed previously (Kaye, 2001).
It can also help in identification of those offenders who while on parole or probation end up committing more crimes. Databases that are relatively small have produced such dividends (Ulrich, 2002). Searches on these databases have been known to unveil murders, rapes and various other offenses perpetrators. Consequently, this law has been known to have some validity which will be fully addressed in the paper.
