What's your question? If you're asking what can be done, you can file a complaint with the agency that employs the officer. Or, you can ask that the Court sanction the officer for being untruthful during the trial. You should talk to the attorney that represented you at trial about all of your options because they will be most familiar with the facts of your case.
Every situation is different and no one should rely solely on information received from the internet. If you have any questions about your legal rights, you should consult with an attorney that practices in that area of law. Nothing in this message should be construed as creating any type of attorney-client relationship.
