Note the complainant has no actual authority to compel the State to dismiss a case. Rather, the prosecutor has absolute authority to continue, or not, the prosecution of any criminal case in Bryan|College Station or any other area of Texas. However, in the right situation a non-prosecution affidavit from the alleged victim can go far in giving the accused person negotiation leverage. That is, many times the prosecutor does agree to dismiss the case, or sometimes reduce charges, based on the wishes of the victim. But in other cases, like those involving serious violence, I've seen prosecutors give a non-prosecution affidavit the "circular file" treatment. That is, no value whatsoever.
So, when speaking with your criminal defense attorney about the issues in your case, don't forget to let them know if the alleged victim might be willing to sign a non-prosecution affidavit. Be very careful, though. DO NOT attempt to persuade, convince, or coerce an alleged victim to "drop charges." There are criminal laws prohibiting retaliation against a person who is a victim or one who reports the occurrence of a crime. You could be prosecuted for a serious felony offense, like retaliation, if you said the wrong things or inadvertently frightened the victim. LET YOUR LAWYER handle this matter after consulting with you.
