The phrase "alleged to be guilty" implies that someone is suspected of committing a crime or wrongdoing, but it has not been proven yet. There are several synonyms that can be used instead to describe this situation. One alternative is "accused," which means that someone has been formally charged with a crime. Another synonym is "suspected," which suggests that someone is believed to have committed a crime, but there is not enough evidence to prove it. "Implicated" is another option, which means that someone has been involved in a situation that is under suspicion. Regardless of the word chosen, it must be used with caution so as not to make unfounded accusations or assumptions.
