Re: "Notably Apple appears to be missing"
Um, have you forgotten the whole iPhone decryption affair we had a few months ago ? Where the police were practically stomping their feet to get Apple to decrypt a phone, which Apple refused, and then the police somehow got the phone decrypted and (IIRC) there was nothing incriminating in it ?
Apple is quite proud of ensuring people's secure communications - unless we're talking about China in which case Apple is just a proud to ensure government access.
I'm guessing that that irks American politicians to no end, but in the US you can't lock up and torture someone to get information - not on US soil anyway. You have to be abroad for that, and the suspect cannot be white.
