And explain that people who know Maurice, know him not to be a risk and ask the authorities to be imaginative about alternatives,
It has presumably been proven, beyond reasonable doubt, that the man is indeed a risk, has ignored previous sentences and is therefore in prison as punishment. What's more, he has left a wealth of ramblings, threats and false accusations on the internet which anyone can read should they wish. I think that would make it nigh impossible for a campaign, such as that you suggest, to have any chance of success.
