Turning in a bunch of money when you could keep it doesn't
make somebody an honest person, since it's one action. A
cop who turns in a million dollars has bought his right to do anything corrupt he wants to do by making himself look like he is honest all the
time (which is what honesty really is, honesty at all times, when nobody cares or pays attention). The truth is,
nobody is honest one hundred percent of the
time, it's really a matter of what degree of honesty somebody usually gives you when they have the option to be dishonest or many other things that lets you know what degree of trustworthy kind of person they are.
