Yeah, but that _doesn't matter_.
The domestic TLA can't afford to embark on massive, wholesale fixing
expeditions this way, even _with_ the escrowed part.  The point is to
fix the unescrowed part at such a size that they can afford to crack a
limited number of keys in a reasonable interval.  Say, at a cost of
about $10000 / key.  That's peanuts for an OKBomb or WTC bomb case,
but it gets to be expensive (hard to hide the expense) if you're
fishing for dirt on members of the opposition party, or investigating
14 year-old Black Panthers.

It also suggests some interesting (and admittedly, abusable) TV shows.
