""slick and effective propaganda machine being run by Daesh"
I must have missed that. The only propoganda [sic] I've seen has been along the lines of "Join us and you get to rape and murder innocent foreigners (fellow Muslims mainly, but don't worry, they aren't *proper* ones) for a year or so before being bludgeoned yourself by the armed forces of the countries you've chosen to attack.".
The evidence is that this appeals to at most a few hundred disaffected teenagers out of a population of millions, who are resistant to the counter-propoganda [sic] not only of their own age group but also their parents and wider family. So yeah, they're really going to sit up and take notice if The Government starts telling them what to do.
So did the whole select committe [sic] sign up to this verdict, or are some of them *not* utter cretins?"
The problem with this viewpoint, and it's not just your viewpoint but held by a lot of people in the UK, is that more or less every fact and piece of information in it is false. Let's start with this:
"I must have missed that.

I thought it was well known that Daesh has a large social media presence with many audio and video releases of high quality, but it appears not. They are very good at it, and strangely enough don't mention any of the downsides when asking people to sign up.
"The evidence is that this appeals to at most a few hundred disaffected teenagers out of a population of millions, who are resistant to the counter-propoganda [sic] not only of their own age group but also their parents and wider family.

No. The UK, despite having many more Muslims of a background that would suggest susceptibility to propaganda, sends fewer fighters to Syria than Germany, per head of population, and half as many as France. The evidence is there that Prevent, working alongside the other three strands of the strategy (Pursue, Protect and Prepare), succeeded in lowering the terrorism and extremism threat that faces the UK.
"So did the whole select committe [sic] sign up to this verdict, or are some of them *not* utter cretins?"
You've been reading about this for at least ten minutes, and read the whole of this article, so of course you know more than the people in the Select Committee about this, who only had these boring briefing papers and reams of documents to leaf through.
I really do fail to see why the general population, who normally have no particular knowledge of an area, think that they are equally qualified to voice an opinion about a topic as those whose job it is to work in the area, and furthermore to brand them as 'utter cretins' on the basis of the flimsiest of evidence. This anti-expertise-ism lay at the heart of Michael Gove's 'Britain has had enough of experts' statement. What do experts know, with their education, years and experience and knowledge of the area? You can prove anything with facts.
