Answer:
As a democracy we hope that citizens will have a voice in who keeps things in order. We choose what we believe in and pick who's best fit to continue a fair and equal society. Without this idea that we have control of ''peace'' we would all go into a killing frenzy. The idea of law keeps us in order and we pick who manages it.
The whole reason we changed from a monarchy to a democracy is because we like believing we have a say in our lives so to continue living like how we want to we must have a say.
