The new law, which goes into effect on January 1st, has been billed by the government as a way to help the police track down repeat offenders. It lets the police collect DNA from anyone suspected of committing a crime that could result in a prison sentence, regardless of whether the sample is needed for the investigation.
If the suspect is convicted and sentenced to prison, the police will keep the DNA sample in a database. But they must destroy it if the suspect is acquitted or merely given a fine.
The police will also have the authority to demand samples from people whose DNA may be helpful in solving an investigation even if they are not suspected of a crime. Those samples are to destroyed when the investigation is finished.
