It was a fake check. The cops arrested Haldeman when he tried to deposit it, as it was apparently the "evidence" they wanted to establish intent to commit a crime (blackmail, not fraud).
But, I'm still skeptical. The prosecution is going to have to prove that Haldeman intended to harm Letterman if he didn't buy the "screenplay". Unless he made the threat explicitly, I'm not sure that charge will stick.
Haldeman did do one thing wrong: he reportedly "contacted" Letterman by leaving a package on/in his car. He should have sent it FedEx, if he wanted it to look legit.
Cops helped Letterman in fake check sting operation to nail Haldeman ? And Halderman is ex- boyfriend of Letterman staffer ?
This is gonna get real good —
Another consideration
The police had Letterman’s attorney meet one more time (before the check was handed over), specifically for the purpose of getting Haldeman to say that he knew this was illegal, and was backmail, and reportedly Haldeman said, yes, he understood. This is supposedly on tape.
