Re: Dear Courts. No. Go away.
But you fail to mention things such as whistle-blowing, revealing state secrets, organising protests, avoiding punitive import duties and many other things that are illegal only because they are inconvenient, embarassing or damaging to the government.
So what, we just won't bother having laws then?
This is why we have courts and an independent judiciary. You can't say "Oh well, companies shouldn't help Police investigate crimes because some laws are unjust/politically motivated".
There is a place for strong encryption, and for whistleblowers (also protected by law in most civilised countries) to be protected. That's why the idea of a company helping Police with a specific warrant signed by a court is not abhorrent. By contrast, providing a datastream for Police/authorities to speculatively poke around or go fishing would be.
Do you believe that you have a moral duty to report your friends, neighbours and/or relatives to the police for breaking lockdown rules?
I'm not subject to a warrant requiring me to. I won't go to prison for not reporting them. But if I were culpable... I"m not going to be a martyr for some tit deciding to have 15 people over at Christmas.
It also assumes that the police will only ever make use of the facility to fight crime, and would never invent a pretext to use the power to go on a "fishing trip" or be abused by a government to learn confidential information about major companies or political opponents.
It's subject to a court order. This is not Police going on a fishing trip - the independent judiciary have signed off. You cannot ask for better than that.
The police in the UK have the power (RIPA section 47) to force a person to decrypt any data they have access to, with up to 5 years in prison should they refuse. So instead of demanding that the service provider decrypt the emails, the police already have the viable alternative of demanding that the person who sent or received the emails do so. This is more than enough power.
Except this is in Germany. But for an equivalent case here, that won't necessarily get them the emails. A defendant may know that the contents of their emails are worth a damn sight more than 5 years in prison. Police might pursue both avenues - and if they have a court order, then that's entirely fair enough.
I'm in favour of strong encryption and strongly against farcical "backdoors". But I equally don't expect service providers to do time for me if faced with an actual court order backed by a judge (in Europe, none of this nonsense with picking judges and jurisdictions in the US). If it's specific and targetted, such it up. Lavabit did, and so will most orgs.
