I&#x27;d argue yes, simply because many anti-terrorism laws are vaguely enough written to make receiving money from, providing support to, or heck even communicating with (in some circumstances) terrorist organisations can be illegal. Plus then you have wire fraud, regular fraud, and a bunch of other financial crimes.<p>The real question however is not &quot;is it legal,&quot; the real question is &quot;will anyone prosecute me?&quot; Jay-walking and speeding are illegal too, but people often do it because they know their chance of being caught and punished is relatively low.<p>If a prosecutor knew you scammed a terrorist organisation, while I&#x27;m sure they could find something to nail you with, they might decide it isn&#x27;t worth while. But then again, misunderstandings seem highly likely with this kind of scam, and they might claim that you yourself thought it was a real explosive device or planned (future tenths) to build one.<p>So I guess, even if you &quot;could&quot; I don&#x27;t know if you &quot;should.&quot; It only can really bite you in the butt.
