Re: No, it's not settled
Sir Tim needs to assist with finding a way to allow law enforcement authorities to monitor Islamists and child porn purveyors.
First off, I reject the idea that people need to be "monitored." People should be assumed to be innocent unless you have reason to suspect otherwise. And the Government should not be allowed to go fishing for terrorists. But once you reasonably suspect that someone is a kiddie-fiddler or a terrorist, just infiltrate their end-points.
End-to-end encryption only protects the data in transit; once it arrives it's generally saved as plaintext. Surely the Government have RATs (Remote Access Trojan/Toolkit) which they can deploy to paedos and terr'sts' computers, after obtaining the proper warrant, either by social engineering or technical exploits.
We shouldn't allow the NSA to monitor everyone around the world in real-time, but this is a technical problem and a technical solution surely exists.
Knives must be sharp in order to cut things - if you dull a knife so that it won't cut people then it also won't cut bread. So you can't legislate a knife that cuts bread but doesn't cut people because the sharpness of a knife is the defining quality that make it useful.
Weak or backdoor enabled encryption is the same as a dull knife; it just won't cut it.
