Can you see who has a class A license and see what their applications contained?

I would think maybe if you carried large sums of cash with you at all hours of the day and night, perhaps you operate a vending service and collect the coins and transport them to the bank. Perhaps you often receive cash payments from selling food at ball games and make daily deposits. Perhaps you need to go in the dark alleys to take meals to the needy. Perhaps you sell expensive jewelry at swap meets and could be a target.

Chances are whatever need you come up with will not be investigated too far. I'd come up with a realistic need though.

Just don't tell the chief you carry large sums of cash resulting from your drug sales in seedy neighborhoods...
