In the summer of 1972, after seven years of running a successful business importing running shoes from Japan, Phil Knight was about to release Nike shoes to the world. The National Sporting Goods Association show in Chicago was going to make or break Knight and his fledgling company.
Despite their cool “swoosh” logo (which they paid a local artist only $35 to create), a unique company named after the Greek goddess of victory and bright orange boxes of shoes that stood out from the crowd, they had crooked logos and completely flawed shoes. With everything riding on these shoes, panic set in among the employees attending the show.
But a funny thing happened. As the buyers came through the Nike booth, peppering the employees with questions, they bought the hell out of the shoes, flaws and all.
One of the longtime salesmen asked one of their biggest accounts what was going on.
“We show up with this new Nike, and it’s totally untested, and frankly it’s not even all that good – and you guys are buying it. What gives?”
The man laughed. “We’ve been doing business with … you guys for years,” he said, “and we know that you guys tell the truth. Everyone else bullshits; you guys always shoot straight. So if you say this new shoe, this Nike, is worth a shot, we believe you.”
“Telling the truth. Who knew?” said the longtime salesman.
[Note: Shoe Dog: A Memoir by the Creator of Nike is one of my favorite business books of all-time!]

If there is one thing I have learned in the past eight years of running my own private investigation firm, it’s that this business is filled with bullshitters.
Trust is a funny thing. It’s earned. And unfortunately for our business, we haven’t done ourselves a whole lot of favors.
So can you trust a private investigator?
Absolutely! As much as you can trust anyone else.
But there are some types of investigators that I would be particularly wary of.
“We have ‘operatives’ everywhere in the world!”
There are very few firms that have actual employees around the world. Hiring subcontractors in different parts of the world is a common practice and totally acceptable, but lots of firms like to pretend that they have people standing by the phone in any part of the country or world waiting for a call.
“We are a ‘full-service’ agency and can do everything from executive protection in Zimbabwe to a capital murder defense in Kalamazoo, Michigan, to a forensic review of a hard drive in Valencia, Spain.”
The reality is that you can’t be great at everything. And if you really think that you are good at everything, you are kidding yourself.
So, would you rather hire a firm that was mediocre at a bunch of things or great at the one thing that you need them for?
I know whom I would rather hire.
“We guarantee results!”
What did Benjamin Franklin say more than 200 years ago? There are only two things certain in life: death and taxes.
In this business, there are no guarantees. Investigators can guarantee that they will seek answers in the best possible way they know, both ethically and legally, but there are no guarantees that they are going to find that witness, force him or her to talk and have the person sign a statement of confession. Firms that do resort to guarantees may resort to illegal, unethical methods to ensure their “guaranteed” results.
Phil Knight got his multibillion-dollar business started based on honesty and trust; if you are looking to hire a private investigator, it may behoove you to look for those qualities as well.




The UK has no licensing or requirements to become a P.I. so in theory you could be hiring someone who self trained by watching the entire back catalogue of Magnum PI.
The best way forward here is to use someone who is a member of the ABI, IPI or WAPI.
And on the subject of “Guaranteed results”, how can you guarantee to catch a cheating partner if the client is wrong in their belief. The best you can do is provide a comprehensive report of what the person does. Even then many clients will believe you missed something, or you just picked to wrong days etc etc.
Great article as usual. Bravo, Brian for simplifying business and investigations to their core!
Thanks Ed!
I got swindled recently as I tried to locate a lost family member. Unfortunately, I had spent so much money with the fake PI’s firm that I can no longer attempt to search for the family member. I totally trusted the PI when in reality he was just looking to make a quick buck.
You should always to check to make sure you are dealing with a licensed investigator.
How does one go about checking for a license? Is there a database somewhere or some state department/division that one can contact to find out? What entity even licenses PIs?
Many, but not states license PIs. In what state are you interested in finding out if a PI is required to be, and is, properly licensed?
That should have read:
“Many, but not all states license PIs.”
California and Maryland! Thanks, Joe!
Here is a link to verify a license in California (http://dilgnt.gr/2mJ6DaZ); it looks like you need to call to verify in Maryland (410-653-4200)
Thank you so much!!!

Great article, as always, Brian.
Unstated in the first two points is that the subcontractor in an obscure location is often unlicensed. Or that sending an investigator to that location means he is unlicensed there because of lack of a reciprocity agreement–if he’s not flat-out working illegally because of lack of a work permit… In a civil matter, opposing counsel of any quality will challenge evidence that is gathered illegally and the case goes *poof*.
Always go with the local agency, esp. in a matter requiring a particular professional focus or skill set. It might take a little longer to do the basic research, but it pays for itself in the long run.

Excellent point Darryl. It’s best to always use someone who has specific in-country knowledge and experience.
