" were foiled as jihadis moved to crypto communications platforms."
the jihadis moved to encrypted platforms years ago, we were told this after Charlie Hebdo, we were told the same after London, same after Madrid, same after 9/11, same even after much earlier attacks eg Oklahoma City. Snowden's leaks showed that NSA were already in possession of jihadi anti-surveillance manuals, which had exactly the same tips and tricks as the NSA/GCHQ gave to their own agents.
Truth is that unscrupulous people with their own power-grabbing agenda will use any opportunity including (or even especially) tragedies with large loss of life to further their agenda and grab more power. Nothing has changed.
