that's amazing! What a use for PI skills. And I'm sure for some families just knowing their loved one is safe (even though they're living on the streets) is a relief. Heartbreaking, but still. So glad the books resonated. They're super easy reads, but I still reference them often, years after I originally purchased them. I like that the authors acknowledge the power (and danger) of their skills and how they use them to help people stay safe, particularly women. I've done documentary work with women at safe houses and shelters before and the fear of an abusive spouse is no joke. 

Since we're usually not too deeply entrenched in the "system" I don't know when we'd need the help of a PI, except in using these skills for protection. That said, you never know when we may run into a situation for a PI. 

I would think the biggest service to digital nomads from a PI would be in the avenue of one of the authors who takes on private clients who simply want more layers of protection around their personal assets from identity thieves or governments. They're still playing by the laws, but want to put layers in front of themselves. And updating this approach for the digital world we live in. Just helping everyday people -- and digital nomads-- understand why personal opsec is so important and how the basics are a must is a huge help for people. I'd start there-- and from a PI's perspective, that would be so powerful. 

Thanks for diving in! ;)
