I did wonder the same thing early on.
I have watched interviews with Tony Bobulinski, and my impression was that, in that world in which he works, players get as close as they can to the line of legality while remaining legal.
Or at least, that is the goal.
In his case, Bobulinksi was brought in to be the “legal” face of things for the Biden Crime Family, and as time went on, he began to realize his role was simply to provide a veneer of respectability, and when he began questioning things and pointing out things that could be viewed as unsavory, he got major blowback from the Bidens et al, until he reached the point they were excluding him as much as they could while still keeping him on for the sake of the veneer.
Eventually, I believe he understood the nature, and realized if he stayed on, he would be viewed as co-conspirator in illegality, and he cut ties. Their treatment of him in the latter stages only cemented his resolve.
In the interviews I have watched of him, he did not in any way come across as a crooked individual, but one who took a job with a prestigious family name, only to discover the real truth over time.
That is my impression of him.
That sounds plausible. I haven’t been entrenched in this facet of the whole situation recently. But when he first appeared on the scene s couple years ago, I did pay a lot of attention to him and what he had to say. He convinced me then that he’s on the up-and-up.
