42 Days fantastic

Anthony Barnett (London, OK): There is a good post up on the CentreRight blog at Conservative Home on 42 days by Andrew Lilico. He makes the point that in terrorist cases the likelihood of a successful prosecution could be dropped from 50/50, so that suspected terrorists could be charged on prima facia evidence. He understands the point that I have tried to lay out in full in my essay 'An Abundance of Caution'  that this is about protecting the innocent - and that most people arrested on suspicion of terrorism are innocent.
But there is a fantastic response to Lilico in the comments by Alexander King. Maybe a few "potential" terrorists will be rounded up, but the rest of us will be freer as a result. King writes:
"Let's stop pretending this legislation will be applied willy nilly. It won't. This may be frightfully unpolitically correct but if you're not a Muslim man aged between 18 and 35, it won't affect you one jot.
Why everybody is pretending that this legislation is directed at anyone other than Muslims, I don't know."
There is a minor point and a HUGE one here! The smaller is that King is technically incorrect, all sorts of regular non-muslims will be arrested and held without charge. But this is almost beside the point. Muslims are part of everybody in this country, by the million. The moment they believe that the legislation is directed against them becasue of who they are and not what they have done, we are all lost. It is essential that legislation is never directed against groups: has King learnt nothing?
