Whenever you have retained an expert witness to testify in your case—whether in deposition or at trial—you need to prepare yourself and the expert. Don’t just sit back and assume that the expert, who many have testified many times before, has it all worked out. You need to be up to speed on his or her testimony and to make sure the expert has enough information to be effective.
When corporate goes criminal, i.e., an investigation involving a corporation leads to a criminal case headed to trial, you often need computer forensic experts to testify about the evidence. Such experts know all about electronic devices and data storage and retrieval, but they don’t necessarily know how to clearly relay that knowledge. It’s up to you to prepare your computer forensics expert to testify effectively.
