The challenge was to my words, ".. use a mobile phone or internet phone.
Those are rather more difficult* for an unspecified group of people to
intercept." *Than a land line.
I would suggest that those words are correct. Specified groups, such as
Government Agencies, are a different matter.

Thank you. I would suggest, "not as easy as tapping a land line" as
alternative wording.

I thought it was part of Fylingdales - or maybe it's GCHQ in Cheltenham

Properly done taps are impossible to detect.

| Why would anyone do an analog wiretap?
They would if the line is analog. But even if digital, a poor tap can
still be detected by using a TDR which would be pushing an analog signal
on the wire and watching what comes back.

I had a guy quite seriously ask me (5-6) years ago if it
was possible that his phone line was being tapped. He'd
heard strange sounds... I laughed and told him if it
was, he'd never know it.
Of course then we got into a discussion of what would
cause his line to be tapped... His son was married to a
Chinese lady who happened at the moment to be in
Indonesia. He was a 747 pilot flying into Afganistan
and Iraq, with a long history of employment by the
Kingdom of Saudi Arabia.

It's cheap, easy, fast, and convenient for those who want to tap a line
without going through the official legal channels, red tape and associated
paperwork that would usually stop you anyway.
