The idea that moves like this will "keep us safe" is utterly preposterous; there are a multitude of other ways in which terrorists (or the boogeyman de jour ) could communicate - are the UK and US governments going to insist on backdooring IRC, Slack and face-to-face conversations? Are they going to outlaw encryption libraries? I truely fear for the future that western governments, in particular the 5 eyes members, a…
The keeping safe argument from government is indeed preposterous. As if that was their mission to keep us safe. Why are they allowing our nature to be destroyed in favor of money/economy? This years heatwaves killed many thousands of people in Europe only, some estimates are in the tens of thousands. This is real deaths in 1 year, not because of terrorist attacks, no fucking backdoor will stop this. And what are they…
I don't think it is quite as simple as this (I'll preface this with saying I don't think we should have backdoors and that I wish we had STRONG encryption everywhere). I think the problem is that different departments have different goals. It is very clear that the CIA and NSA's jobs would be easier if there was a magical tool that let them backdoor in and no one else. The police and FBI would have an easier time doing their job if encryption wasn't a thing. That's definitely true! The issue is who is watching the watchmen? That's why we need checks and balances (specifically by people that understand the tech). These departments are so focused on their goals that they lose track of the fact that introducing backdoors actually creates more work for them (and thus actually makes their lives harder). But as humans we're always focused more on the task at hand and less on the over arching tasks (we're notoriously bad at dealing with large scale multifaceted problems). It all really comes down to these departments thinking "if we had this tool it would be possible that we could have stopped this" (which possible is the key word, because we've seen that they can't. There's just too much data. You're just adding more hay to the haystack). The failure really is at the checks and balances stage, that those watching the watchmen don't understand the motivations nor the consequences, and thus let them do as they please. Agencies running the checks and balances are supposed to be suspicious and critical, not friendly. But these agencies aren't getting the funding nor can they attract those that are tech literate, so there's a feedback loop that is only getting stronger. What I'm trying to say is that there's this long chain and things are broken at many stages and that if a single stage was fixed there would be significant improvement. Basically solving at any single stage will help stop the feedback loop.
tldr: The intelligence agencies should be smart enough that they would know that backdoors will backfire on them. But they clearly aren't. There's also a huge failure at the checks and balances stage where these agencies are getting approval which creates a feedback loop and without solving this the problem will continue to grow.
