I don't mean to admonish you, sorry. You are perfectly entitled to state your view, any view on any subject. For sure. Your mistake, for want of a better word, is to have the wrong mindset about investigating.
With criminal or civil (or, torts) investigations it is all about the same thing: revealing the facts.
Yes, you can call them "baddy" and I call them worse sometimes, but only in my mind, because as an investigator I am (or rather, was) conscious of the importance as being impartial and acting with balance, without prejudice, knowing that if I am recognised as being a mongrel, it will taint the evidence I am gathering. This would not be in my client's best interest.
An insurance company does not ask you to investigate "a fraud", but asks you to "investigate". If your investigation reveals criminal evidence, then you pursue it in a balanced and impartial way.
An insurance company's objective is NOT proving that a claim is false, but revealing all the legal evidence so it can be determined whether the claim is or is not false, or more typically, whether the insurer is liable or not (mostly you investigate liability, not fraud).
The insurer is better served by knowing all of the facts, for or against the claimant, than have an outcome where the investigator chased hard for anything that will drive a nail in the claimant's coffin. Having been in court many, many times, I've learnt that outcomes where the investigator was pushing hard for a "win" more often fell over, than investigations where the investigator remembered that he is a gatherer of facts. Nothing else.
You do not have a sword; you do not need a sword. All you need to do is walk along and gather. With good people skills, people will want to cooperate with you. I found this the case with nice and normal people and with those that seemed to be bad.
Excuse my poetic licence.
