The only other journalist who was there made an interesting point, that encrypting cell phone traffic only up to the point it hits the phone system wouldn't hinder L.E. access but would protect privacy. (Or, perhaps, would be worse in the long term since we wouldn't have such luscious examples.)
This is well-known. GSM does this, for example. I've seen the point made in several textbooks. I don't know of any cellular systems that do end-to-end encryption (which would stop wiretapping at the landline switch) as opposed to airlink encryption. Does anyone else?
