I have been listening to this Catching the Kingpins podcast from the BBC, exploring the encrochat case and how the police used this to catch some serious criminals. The series details how the hack happened, cases of who they managed to snare with the operation (from mid-level drug pushers, to high level importers and money launderers), the people behind encrochat and more. The sophistication of the criminal operation makes dodgy Dave look small time.
