Yes. Without having the two lists of offences before me, I can't swear that they're identical lists. There may be some things that relate to DNA collection that aren't necessarily sexual offences, but it is not uncommon, I would suggest, to have an offender who's subject to both of those orders at the same time.
Of course, in drafting the legislation, as Mr. Hoover has indicated, DNA legislation was already in existence and provided some guidance to Parliament.
