Assuming that the officers noted the drunken state of the witnesses, this should have been addressed in the statements, as it can impact the credibility of the person giving the statement. Discuss this with a local lawyer who can review the reports and the statements to evaluate the potential evidential value of the witness statements against your own. You can then make an informed decision on how to address this matter in Court. Good luck.
