State v. Blow
In State v. Blow, 157 Vt. 513, 517, 602 A.2d 552 (1991), a police informant was wired with electronic transmitter and sent to the defendant's house where he purchased marijuana.
Defendant moved to suppress the tape recordings of the transactions and the officer's testimony about them.
The judge allowed the detective to testify about the conversations between the informant and the defendant at the time of the sale. The recordings themselves were not introduced.
In deciding the case, the Court acknowledged that the "assumption of the risk" would preclude any finding of a violation of the federal constitution.
