There's always the possibility of just asking said non-tekkies:
- If the government can't keep their secrets safe (even ignoring
various insider attacks like Manning or Snowden, let alone that which
happens at the hands of disgruntled law enforcement officers or
curious medical practitioners; see e.g. the recent US _Office of
Personnel Management_ breach, or the illicit telephone wiretapping
mess in Greece a few years ago which AFAIK hasn't ever been attributed
- If the companies that make software designed to allow spying on
people can't maintain security (see e.g. the recent _Hacking Team_
- If large multinational corporations can't maintain security (see
e.g. the recent _Sony_ episode),
- _Then why_ should we trust any of those to, in addition to their own
secrets, keep _our_ secrets safe? Why should _I_ trust them to keep
_my_ secrets safe?
I obviously might not be able to do _better_ (and frankly, am unlikely
to be able to do significantly better) than any of the above, but at
least I'm not creating an _additional_ extreme-value-target treasure
trove which I then fail to adequately protect.
I sometimes compare data encryption to locking your house. (Most
people accept that, even though they aren't doing anything illicit in
their homes, they don't want strangers rummaging through their
belongings.) In that comparison, "exceptional access" would be a sort
of global master key that allows trivial unlocking of _any_ locked
door, in such a way that does not trigger any alarm system or anything
else similar that the home owner might have installed.
