This idea of back doors being opened up to black-hat hackers seems to be the crux of the current leading argument against key escrow. Even the EFF is beating this drum.
Bear with me, I'm not disagreeing with that argument, but isn't there another point to be made here? And that is:
Key escrow systems ask us to assume that the current "good" guys in positions of authority will always remain good. Isn't that a bit too much of an assumption?
