Frankly, I don't. His judgment on every major issue has proven so utterly flawed, so grievously wrong and so calamitous for the nation that his judgment on the 42 days detention issue cannot be but the same.
And when in the few days between now and the Commons vote next week some security service chief or senior police officer 'leaks' some spin-coordinated new threat to increase Brown's climate of fear - as they surely will - I will trust him even less.
So, let's open a book now. Will the 'news' this week be that 500 Jihadist terrorists are working in the civil service, or that police are now tracking 200 terrorist groups, or maybe a raising of the threat level from 'Severe' to 'Critical' just prior to the vote? Perhaps a high profile televised 'raid' with officers dressed in full NBC kit and residents evacuated? Or will they be clever, and 'expose' an assassination threat to MPs on the basis that even the most liberal backbenchers will find the prospect of having their heads sawn off with a breadknife unwelcome? Let's wait and see.
