I think one of the reason is that the parliamentarians, including many from the DPP, basically told the parliamentarian police that all the occupiers were their guests. They invited them in, and so with the MPs’ immunity from police, and really, the civil disobedience is part of their agenda anyway, they kind of acted as a shield layer, because the police would not hurt the MPs. That’s also what the DPP MPs really helped at that point.
