I think there have been times when concerns have been raised that there may be some officers who played a direct role in some of the violence. Obviously we've pointed to concerns that security officials were responsible for violence in Maspero Square. I've highlighted the concerns about them having reportedly driven their armoured vehicles at high speeds right through Coptic protesters. That's one level.
I think the wider and long-standing concern, though, has been that security forces in Egypt have simply not done enough, and in some instances they have done virtually nothing to provide protection to Coptic communities in the face of violence. They have abandoned them to sectarian violence when in fact they have a binding legal responsibility to intervene to ensure protection.
