While a cryppie center wouldn't help the FBI keep up with strong
cryptography used well, they would find it very useful in dealing
with weak cryptography and with strong cryptography used bozotically.

The recent Denning and Baugh study on how much harm crypto has done to
law enforcement investigations points this out strongly.  They found
that crypto has not in fact prevented successful investigation and
prosecution.  They did encounter crypto, and in each case they were
either able to break it (because it's cheesy McCrypto Wordmaster kid
crypto), or they were able to find the keywords or plaintext somewhere
in the perp's house or computers.

Until we have serious seamless apps, there will be plenty of chances
for law enforcement to get at the plaintext one way or another.  Do
you use your super-4096-bit-RSA-key-international PGP under Windows?
If so, do you disable and wipe your swap file?  Do you use it under
Linux?  If so, do you even know where your swap file is?  The FBI
with a competent cryppie center would.

Just because they couldn't break the good stuff doesn't mean they
couldn't successfully support the vast majority of law enforcement
investigations.

Whether this means it should or shouldn't be implemented is another
question -- perhaps it would serve as a spur to people to use their
tools more sensibly, as well as giving the FBI something more useful
to do than spending public money lobbying Congress.
