Let's just say that there was an incident that may or may not be on the records. Asking former teachers, neighbors, friends and relatives would be great, but again - we're not sure what could be pulled up record wise.
And don't forget two very important things:
1) This is all post 9/11
2) They are swamped with applicants who have literally never done anything wrong in their entire lives. Boring, but just the same..... :P
