A: The necessity for a personal injury lawyer to “prove that the accident or injuries were not their client’s fault” distinguishes their role from a criminal defense lawyer by shifting the focus from proving criminal innocence to establishing civil non-liability and attributing fault to another party. While a criminal defense lawyer aims to acquit their client of charges, a personal injury lawyer’s specific task is to demonstrate that the opposing party’s negligence or wrongful act was the cause of the harm, thereby entitling their innocent client to civil damages. This requires a specific skill set in accident reconstruction and liability assessment.
