hijackers of a truck carrying dog food were arrested and indicted by a grand jury. during the grand jury's investigation. the district attorney's office subpoenaed the truck driver as a witness. to her relief, she was not asked questions about a series of thefts of shipments of dog chew toys that she was involved in, but believes that the subject might be brought up at trial by the defense lawyers. she is afraid that she likely will be fired if she invokes the fifth amendment privilege against self-incrimination on the witness stand, so she wants to avoid testifying at all at the trial, even if she is subpoenaed by the defense. as her lawyer, what advice should you give her about complying with a subpoena?
