An example would be you have the right of keeping your bank account activity shielded (private) from the government by default. But, if you are participating in human trafficking you lose that right (it's not absolute) and the government can go in to track your activity to prevent further human abuse.

Of course, this is an easy example with an obvious right/wrong. In the real world situations are all over the place, so our goal should be to constantly strive to find a more perfect balance.
