Question juridique clé
Whether the unlawfully obtained DNA profile could be used as evidence
Solution extraite
Yes. The interest in prosecuting a serious violent and arson offense outweighed the defendant's protected interests, and the profile could also have been obtained lawfully later.
Motifs extraits
An unlawful evidentiary acquisition does not automatically bar use; the court balances interests. Here the offence was grave, the DNA evidence was only one element among others, and the defendant did not show that lawful collection of a cheek-swab profile was impossible.
