Well i am on probation and the dna
test is for making sure that everytime u go in to get swabed (drug)
test that the dna is from you, apparently somone has tried to foil the swab
test in probation the standards are up to date, and the fbi can use this if your dna is linked to a past crime or in the future, so i guess once you are in the system you can never get out, lol i am kinda kool wit my probation officer friend of family (small world) she gave me the whole scoop in this swab shit. hope this helps
