Hehe, again, *you* started all the "bullcrap" about foreign "governments"
in the first place :-)

Ah, so you're qualifying the discussion with the nice and subjective
"adequate" ... (you're still wrong, of course)

Let's stick on-topic here ... remember "securing a system against attacker
with physical access is fairly simple" ?

[ Took the liberty of removing some irrelevant digressions -- didn't see
  any solid security scheme that fulfils/justifies your earlier claim over
  there. ]

No, you didn't -- it was obvious from your reply :-)

                                                         ^^^^^^

But what gave you the impression we're interested in discussing "common"
or "adequate enough" attack vectors here?

See, if you have something useful/new to contribute to the discussion,
that we don't already know, then please don't hold back and feel free to
do so ...
