you wrote "supporting a proscribed organisation" under membership, which she must be nailed on for.
we don't know what literature and/or messages she has been sending back so there is possible recruitment issues as well as handling terrorist publications/literature etc.
and membership seems pretty clear, to me at least

Membership.
(1)
A person commits an offence if he belongs or professes to belong to a proscribed organisation.
(2)It is a defence for a person charged with an offence under subsection (1) to prove—
(a)that the organisation was not proscribed on the last (or only) occasion on which he became a member or began to profess to be a member, and
(b)
that he has not taken part in the activities of the organisation at any time while it was proscribed.
(3)A person guilty of an offence under this section shall be liable—
(a)on conviction on indictment, to imprisonment for a term not exceeding ten years, to a fine or to both, or
(b)on summary conviction, to imprisonment for a term not exceeding six months, to a fine not exceeding the statutory maximum or to both.
In bold are the defences. I reckon 3 kids in 3 years would back her up in the defence that she wasnt a member , merely married to a member. Its going to be bloody hard to get her on the arranging meetings one too.
Lets say we do find the evidence and because of the profile she gets found guilty and sentenced. Firstly she is under 21 so not likely to get the maximum sentence. Then she will have spent time on remand awaiting trial. Then she will get time reduced for good behaviour. Shes out in 3 years max, costing the tax payer to give her a new identity and protect her from" vigilantes" which would be ironic.
I am still convinced she walks. I am cynical and tarnished granted.
