I have worked as a Retail theft professional for many years as LP, Loss Prevention Manager as well as consulted for retailers and helped private citizens like yourself. I am very aware of these databases and how they work. These databases hold your info for about 7 years (varies by database) after that it drops off list. There is no means to remove your name. Now if you were found not guilty in court you might be able to contest the entry but anything less than that it is very unlikely. The good side only other subscribers to same database will have access to the info contained there. In short if place you seek employment is not subscriber they will not have knowledge or means to see your name in database
