Where is the limit?
If creating a backdoor meant avoiding another 9/11, what would be the right thing to do?
I think the mania for "privacy" has gone way beyond common sense: until 10 years ago we were all happily storing our personal info in our houses, in paper, and no one was seriously worrying about someone sneaking in our houses to look at our family pictures, love letters or -oh my God!- our weight.
We too often forget that in 99.99% of the cases NO ONE COULD CARE LESS about our oh-so-precious pictures, messages, etc. There is quite simply nothing to protect, our personal info are valuable only to ourselves.
"Just" give me a common password for all my info/website, and if someones steals my device, big deal, let me make a call and block all access. End of story.
That analogy makes no sense. If the photos, emails, documents, etc. on that device can potentially prevent another 9/11, wouldn't you want law enforcement to be able to access it? You contradict your own argument even before you make it!
