I just want to clarify something: Within the United States, as per the U.S. Constitution 4th Amendment, there is no "lawful " such access to private communications without first obtaining probably cause.
Law enforcement agencies from the EU, North America and Australia continue their work to gain future lawful access to private communications within the EU initiative Going Dark.
We also note that VPNs are mentioned under “key challenges”.

Tho if a US citizen happens to be in communication with a non-US citizen 3-letter agencies can utilise section 702 to college that information.

Make no mistake, i did not say what they will or will not do. I only seek to clarify that when they do it, it is in fact NOT lawful.
