You sign waivers up the ying yang that say anything that comes up in a background investigation, or polygraph, is solely up to the discretion of the department to view as they wish -- and if any reprocussions occur in your personal life as a result (as in, if they notified your employer that you were stealing from them) they are not responsible and cannot be held liable.
There must be 20 waivers you sign, along with all of your paperwork and questionnaires you fill out, most of which need to be notorized.
