John Hnatyschak was a NJ police officer, Derek Poundstone, the pro strongman is a Conn cop. Gary Taylor, the British strongman, was a correction officer. Kim Brownfield, a famous presser, was a probation officer. Chuck Sipes had a job with the California Youth Authority. Dave Johns worked in a similar field too. Joe Palumbo was NYPD, on their SWAT team too I think. Don Reinhouldt worked in Youth Services too. Powerlifter George Frenn was a High School counselor that worked with under privileged kids quite a bit. Grizzly Brown, the Strongman, did similar work too.
Those are the ones I can think of quickly.
Edit - Powerlifters Pat Casey and Marv Phillips worked in Law Enforcement too.
Roger Estep was a paratrooper and medic in Vietnam, he's the guy some confuse with Rippetoe -
