The defense has a right to question a witness who claims he will assert his 5th Amendment right to not incriminate himself. Nothing more helpful for a defense to question a witness who repeatedly take the 5th. Every assertion of the 5thdrives home the point that the prosecution is dirty as hell.
Kind of what I was thinking, having the GVT spy taking the 5th is not good for the prosecution.
A lawyer who attempts to draw an inference by a 5th amendment plea would be sanctioned. It’s a violation of a constitutional right.
