To incriminate someone means to provide evidence or information that suggests or indicates their involvement in a crime or illegal activity. When someone is incriminated, it means that the evidence or information tends to implicate them as having committed or participated in the commission of a crime. This evidence or information can come in various forms, such as witness testimony, physical evidence, electronic data, or statements made by yourself. Incriminating evidence can be used by law enforcement agencies, prosecutors, or other legal authorities to build a case against the individual and potentially lead to their arrest, prosecution, and conviction.
