@aral I don't understand the controversy here, why is it that we fight for regular joes to have access to encrypted messaging but we draw the line at government services? The police (whatever your opinion of them) are currently not meant to be openly transparent, they have oversight boards for that reason.
Whether they are corrupted or not is also out of scope of this discussion, but it seems to me like a double standard to say "encryption for me, but not for you".
