The bank is constituted of several indices, some of which deal with either convicted offenders or DNA collected at crime scenes. Other indices would now deal with the DNA of missing persons or persons who may be dead. All of this is put into, globally, a DNA data bank. The government would be able to cross-match the DNA in question.
Maybe to be clearer, there's a provision in the bill, which is proposed new subsection 5.5(2), which would actually limit the matching of DNA information provided by a relative so that it could be used only for the purpose of identifying a missing person. The provision explicitly says that the DNA of the relative of the missing person cannot be matched against the crime scene index or the criminal offender index. In that way, the distinction between the humanitarian purpose and the law enforcement purpose is made clear in that provision with respect to the DNA of a relative of a missing person.
What I'm suggesting is that the rule should also apply to the DNA of the missing person himself or herself.
