I think a lot of people would disagree with this premise. The argument against it is basically that abuse of powerful surveillance technologies is inevitable precisely because the technology is so powerful. In reality, law enforcement is only incentivized to catch criminals, not necessarily to protect people's privacy or personal freedoms, so LE will abuse these capabilities 100% of the time they have access to them.
A more subtle argument is that bureaucratic oversight of LE is almost always impotent to reign them in and has every reason not to due so due to a lack of accountability. A "fair, ethical" system is fundamentally incompatible with one in which law enforcement has sweeping surveillance capabilities and the lack of oversight which always results from any sufficiently large/slow/complex legal system.
