Solving crimes and prosecuting criminals depends on efficient access to evidence. Technology has not changed that.
What has changed, however, is that much of that evidence has migrated online. Most importantly, it’s often stored overseas.
This is true for so-called cybercrime, and for traditional “offline” acts. For example, prosecuting a murder, rape or child abduction may depend on access to e-mails, search history and mobile phone locations – all data that may be stored on overseas servers.
