DNA crime investergators best friend??

 DNA has changed the way police solve crimes. Now with DNA the cops can get the badguy with just a fingerprint, blood sample, hair sample or anything else the cops find that aint the victums. With the technology now a days the cops will be knocking on the bad guys door before the guy or girl can get out of town. The two main tests the csi guys run on DNA are PCR and RFLP. These two tests help the cops catch the badguy.
