Let me repeat this--and I know that the headings are of no legal force or effect--under “Participating, Facilitating, Instructing and Harbouring” it says: “ Every one who knowingly participates in or contributes to, directly or indirectly, any activity...”. So you're contributing indirectly to an activity of a terrorist group for the purpose of enhancing its ability to facilitate. We're getting about as close to being as broad as you can possibly be, and we're spreading a net without being uncertain.
It's a complaint I often express about the law--why can't the law be a little clearer? The problem is that after many years of courts interpreting sections, to simply put down “undertake” may confuse things rather than help things. As difficult as that is for most of us to understand, the more you try to simplify it, the more confusing it often becomes. So you end up with sections like this.
