DNA part one

I have changed the facts here to disguise the ongoing story. An expensive car was stolen. It was found by the police. An officer swabbed the gear shift. The swab was sent to the ESR. Two dna profiles were obtained from the sample. Both profiles were run through the crime dna database. One of the profiles matched a profile stored in the database. The ESR gave  a report to the police confirming this. The police charged the person with the matching profile with stealing the car. The person pleaded not guilty. The police now needed an evidentiary sample from the accused and applied to the court for a dna compulsion order which if granted would compel the accused to provide a saliva sample. This could be done by force if required. A substantial invasion of bodily integrity, dignity and privacy. To be continued.
