    STARTTLS is not the only encryption solution

    STARTTLS allows for establishing a connection on an insecure protocol and then negotiating encryption. IMAP, POP3, and SMTP all also support encrypted-only versions.

    While IMAP uses TCP port 143 for plaintext and STARTTLS connections, IMAPS runs on TCP port 993 and *only* accepts encrypted connections.

    I'm no government apologist, but railing against the lack of STARTTLLS is a little much.

    time differential

    One aspect that I think has been glossed over when comparing radiation received from a scanning machine to that received during a flight is how long it takes to absorb that radiation.

    A transcontinental flight takes several hours, during which you continuously absorb a little bit of radiation. The scanning process takes seconds, during which you receive (we're told) a similar amount of radiation. Think of it like sunbathing at the beach versus a quick trip to the tanning bed.
