Why?
You have to ask yourself why Rogers bothers. No one at the conference is going to buy the story about the need to have backdoors to catch whoever-- the problem is that they can't catch anyone publicly now despite the deplorable state of Internet security. A cover story is needed for those remailer keys/SIM keys/TOR keys/pickyourfavecryptohardwarekeys stolen long ago... I have it! There is a backdoor for security purposes that we used and here is the evidence needed for conviction!
Yes, indeed, a framework is needed to provide a cover story about how we got the information without actually saying how we got the information; it came from the same place, just not from the so called backdoor. But it could have, and you can't tell it didn't now can you?
It works even better when, say, China installs backdoors everywhere (because the Americans are doing it)... only the Chinese backdoors are real and guess what? The NSA rubber hoses broke the Chinese back doors down before the code even properly compiled! The American back doors don't even have to work to put a torpedo in Chinese security... the NSA/GCHQ will gladly help all comers properly implement a back door.
