I am also completely against this crap but bear in mind that the volume of data will be so huge that no one will even try to read it. No one cares about your email unless they already have a reason to be suspicious. They will mostly likely only use it to intercept and decode transactions and communications of suspected or known criminals. They wouldn't have the manpower to read everyone's stuff. Just think you rarely have time to read your own email, how would a few hundred agency people have the time to read the communications of 200 million+ people?

On this note, in Hungary it is illegal to sell mobile phones to anyone under the age of 18 and all mobile phones must be registered with a full name and address. The mobile networks in Hungary are set up so that the police can tap any mobile at any time and listen in. This may seem like a huge invasion of privacy, and it is, but the people live with it.
Last year a man was gunned down in the city of Gyor. The police listened to every suspect's mobile phone registered in Gyor and after 6 weeks or so, arrested and convicted the killer based on phone conversations they had listened in on. This is proof that it does work and does have its uses, although I am not saying that I like it.
