The bail conditions he's alleged to have breached do seem draconian. According to the BBC:
- Tagged and allowed out of his home only between 08:00 and 16:00
- Banned from traveling on the Tube, or by train, car, motorbike or bus
- Banned from contacting a number of named individuals
- Only family members, his lawyer, emergency workers and social workers can enter his home without approval
- Banned from using mobile phones, computers and other devices
- Banned from attending mosques, leading prayers and giving lectures
- Needs approval to take a job or enroll on a course
- Allowed one bank account and must surrender his passport
Banning him from mosques would seem to be restricting his rights to practice religion unless a visiting Iman is allowed. The ban on the use of computers looks bad too - many services are going online-only.
According to Wikipedia "Regularly imprisoned in Britain as a threat to national security since he was first detained under anti-terrorism laws in 2002, he has not yet been prosecuted there for any criminal or conspiracy offences" but a number of less than savoury governments allege terrorist offences.
If you believe and trust our politicians, he's a very dangerous man. I'm not sure I do.
