According to your description, you are suspected of fraud. The case is clear and the evidence is conclusive. Is it necessary to ask a lawyer to defend this situation? As a bystander, you need to hire a professional lawyer to defend the suspected fraud crime. The case is clear and the evidence is conclusive. Because the Criminal Procedure Law clearly stipulates that criminal suspects and their families can hire lawyers to defend them when trying and judging criminal cases, or the judicial organs can appoint lawyers to defend them. Lawyers can not only defend innocence, but also plead guilty, with the aim of reducing or reducing the sentence when sentencing. Therefore, although the case is clear and the evidence is sufficient and conclusive, this case still needs to be defended by a professional lawyer. At the same time, it can also reflect the principles of justice, fairness and openness of the law. Think for yourself!
