Bob Ball is a real estate investor in Portland, Ore., but that's just his day job. For the past 20 years, he has also been a volunteer cop.
"When I was new, it was the best time of my life. I got to go out there and wear a white hat and help people and make a difference in my community, one little piece at a time," Ball says. "That's a very, very fulfilling thing to do."
This is real police work. On one occasion, Ball had to pull his gun on a guy threatening a woman with a knife.
