"Baiting" the security guy has only as much weight as his unnecessary investigation. They knew the bills were fine but he came to investigate anyway and he didn't just ask "Hey, how'd ya get those bills?" but tried to be sneaky. He was also salaried and got paid for the interaction so he wasn't a victim in the slightest, except perhaps to his ego.
The nasty act here, and possibly criminal, was the security guy calling the Secret Service and reporting on someone he knew wasn't actually guilty of anything.
> It is an ugly story ...
Of tedious security people inflating themselves by bothering normal people.
> it's not an isolated occurence! He clearly does this all the time
Thankfully, if these people go unchallenged then when they go off it's on a random unsuspecting person. He's prepared and can take it in stride.
The mistake was to engage with the SS agent without his lawyer. He pretty clearly wouldn't have been arrested but because he essentially volunteered for this fishing expedition they'll perform it.
