Undoubtedly, new technologies challenge traditional policing, but it is no reason to forgo human rights and becoming more invasive in investigation techniques. New technologies work both sides (criminals/police) as long as one pauses to see their potential. Criminals are very good at it; police forces seem to be less able to view it in a positive light. A shame because hacking computers won't help them tracking down criminals if they do not have previous information of what has been done. Second, having a computer does not give the right to breach privacy. The traditional criminal procedural rules DO apply; thus the Australian proposals look pretty scary.
