The problem is that people foolishly assume that the plaintext packets they send online are private by default. As in real life, good privacy can only be assured by significant effort on the part of the communicants. Is it evil to observe something occurring on a public street corner? It is not different to observe something occuring on a public IP router.
The postal system is a public utility. Should it be filtered? What we're arguing now is why one envelope is special. I put my communications in paper envelope and I'm protected, but when I put it in an SMTP envelope, I'm not. I'd like someone to rationalize that.
As far as I'm concerned, let's do it one way or another. Either protect email or start OCRing the post.
Don't be dense. Letters are easily intercepted and read, but we still expect that the government is not doing so because the constitution forbids that sort of behavior and the judicial branch is supposed to protect us from it.
You're conflating privacy with security. Security requires encryption, etc... privacy exists in the absence of monitoring devices.
If you are "vibrating the air" in public, then yes, you should realize that there could be a microphone nearby that records what you're saying (and in fact, in modern practice, there is a microphone on pretty much every person you see, any of which could be recording at any time).
> people foolishly assume Yes those ignorant fools deserve everything they get for not being security enthusiasts, and for assuming good faith on the part of their government, right?
What I've been wondering about though, is the legal definition of "effects" (noun, not verb). That term seems very broad to me, and should include emails, but I'm not a lawyer.
This is nothing new, read up on J. Edgar Hoover with his wiretapping and files on almost everybody. Sometimes with White House knowledge and approval, sometimes without. All this while completely ignoring that quaint document down the street called the Constitution. Doing things like that is easy if you can hand over a note to someone that starts out "It'd be a shame if people found out about [insert criminal/embarrassing act here]." Information is power.
