1, local lawyers are familiar with the local situation, and whatever they do will be convenient.
2. Finding a lawyer who is familiar with the local public security law will help the trial of the case and smooth the relationship. But if the facts of fraud are clear, according to my practical experience, I suggest that you don't need to hire a lawyer at the stage of public security and procuratorate, which is useless and expensive, and basically useless. Moreover, the lawyer's fees for criminal cases are collected in stages (divided into three stages: public security, procuratorate and court), and lawyers can be hired when they enter the court.
Lawyers only serve clients, and they can't make money without trying their best. If you are worried that the local lawyer will not try his best, you can sign a risk agency contract when signing a contract with the lawyer, which is linked to the agency fee, and he will try his best. In other words, it is written in the contract that if the judgment results in one year's agency fee less and two years' agency fee less, he will have no enmity with the money. In order to make more money, he will definitely try his best to contain him with agency fees.
