Defense attorneys have to advise their clients about their rights. They need to cultivate a deep understanding of state statutes and applicable precedents from similar cases. They may need to assess the state’s case, seek out additional evidence and present a compelling narrative to exonerate their client during a trial.
Sometimes, criminal defense attorneys hire expert witnesses. These outside professionals may play a critical role in the overall defense strategy for a client. Why do lawyers bring in expert witnesses during a criminal trial? Here are some important reasons:
1. To explain complex information
The mark of a true expert is the ability to take a difficult and complex idea and make it accessible to others. Expert witnesses can help explain complicated forensic evidence or financial records in a way that makes sense to the average juror. Their specialized knowledge can make explanations more compelling than similar explanations provided directly by a defense attorney.
2. To identify evidentiary issues
Accurately reviewing evidence requires special training. Police departments and prosecutors may work with specialists ranging from forensic pathologists to accountants to support allegations against a particular defendant.
Expert witnesses who analyze the same evidence might discover issues with how the state analyzed the evidence. Problems with evidence storage and collection can also come to light thanks to the intervention of an expert witness. Questions about the usefulness of certain evidence can weaken the state’s case substantially, making an expert witness’s insight critical.
3. To raise a reasonable doubt
In some cases, expert witnesses can analyze the same evidence as the state and reach a vastly different conclusion. In an embezzlement or money laundering case, for example, they might notice in the previously-overlooked transaction that implicates a different person.
They might be able to draw attention to certain details about the evidence that raise questions about whether the defendant could have committed the crime or that seem to connect a different person to the criminal incident. Expert witnesses can weaken the state’s case, make evidence accessible to jurors and even help identify alternate suspects.
Those hoping to fight pending criminal charges often need the insight of experienced legal professionals. Working with an attorney to develop a criminal defense strategy may involve a review of evidence and even the support of outside professionals. Those who respond assertively to charges can increase their chances of avoiding a conviction.
