When conceiving a novel involving legal fraud, the protagonist can use a variety of misleading statements to shake trust in a case. Here are some possible plots and strategies: 1. **Falsified evidence**: The protagonist can claim to have audio or video recordings of key moments in the case, but these evidence are actually fabricated. He can use technical means to create seemingly real audio or video to confuse the audience. 2. **Witness disparagement**: The protagonist can spread rumors about key witnesses to question their credibility or reputation. For example, the witness's criminal history or moral stains can be fabricated to greatly reduce the credibility of his testimony. 3. **Selective statement of facts**: When presenting the facts of the case, the protagonist can deliberately choose only the parts that are favorable to him and ignore unfavorable evidence to mislead the public or jury and cause bias. 4. **Complex terminology and legal loopholes**: Use legal terminology and technical details to confuse the facts, make the case appear extremely complicated, and make it difficult for ordinary people to understand, thereby casting doubt on the victim or witness. 5. **Spread false news**: Spread false information or unconfirmed reports through media or social network channels to influence public opinion and the atmosphere of the case trial. 6. **Creating a scapegoat**: Create a completely innocent but seemingly suspicious scapegoat to divert attention and suspicion to the real perpetrator, buy time or cover up the truth. 7. **Fabricating motives**: Claim to have discovered the complex motives behind the case, distort the original simple events, and describe them as part of a larger conspiracy to distract attention. These strategies can help the protagonist manipulate the progress of the case in the novel, influence the legal process, and shake the trust in the case's verdict. However, when designing the plot, it is necessary to ensure the plausibility of the plot and the gripping narrative method to enhance the tension and readability of the novel.
