My name is ***** ***** I would be happy to address your legal question today. I am sorry to hear the issues you are facing with your ex-husband. The information he is accessing is stored in several different databases. These databases includes LEADS and NCIC. For our purposes, the names of the databases are not important.
The important part of this is that these, by LAW, are only to be accessed for genuine law enforcement purposes only. No officer can access the databases for non-work related purposes. These are always violations of the police departments procedures and general orders. In fact, every search conducted by a person is tagged as searched by that person, meaning a search can always be traced back to the person initiating the search.
As for penalties, there is no crime on the books for this specific act. The usual course is internal discipline/punishment from his employer. In rare circumstances, prosecutors may find a law to charge your ex-husband under. For instance, a charge of "Misappropriation" or "Unauthorized Use of Property" can be charges that are generally charged. However, there is no actual crime that is specific to the use of the databases for non-work related reasons. However, there will still generally be punishment internally.
Please let me know if you have any follow up questions. I would be more than happy to answer them. If not, please remember to click "accept" and leave positive feedback so I may receive credit for assisting you this evening. Thank you and have a happy Thanksgiving!
