dna has changed our world. using dna can catch a criminal in an instant. if you have the right match you can put the rapist, murderer or whoever behind bars. but what if you dont get the exact match of dna. what if all the dna strands match except a couple? what that means is that this person didnt commit the crime, but someone very close, blood related, might have. does the FBI have the right to investigate the relatives of convicted suspects, or is that invasion of privacy? i think it should be done. if it helps put criminals in jail.
