Re: "strongly encrypted platforms are often used by pedophile rings, drug kingpins and terrorists"
Truly unbreakable encryption is trivial, although can get quite cumbersome (a one-time pad handling all 256 values for a byte requires 64K per plaintext character, which means a DVD could hold enough data to send about 73K of plaintext). So fundamentally what "law enforcement" are asking for are ways to snoop on suspects that are too lazy or stupid to use better privacy tools, so by definition _not_ the biggest threats.
