I wish it were that simple.
Many, if not most of the time, CPS cases are of a legitimate concern.
However, all it takes is a vindictive person to call CPS from a few different numbers to complain about you, and they show up by default and you are at risk of losing your kids regardless of your capacities as a parent.
yes.. thanks for your comment.. there lies the problem.. that once they are put on the trail.. they are TOO motivated to remove even without good reasons..
