NCWatcher, I am little confused,as not living in America but due Gammon's Dad and Mum's employment there would have been a security check on family and partners.
Unless TS lied about her criminal record which is possible. IMOO
I have a family friend much older than me who lived a rather interesting life in the eighties she met her husband who was in Army Reserves in Australia, he had just accepted his promotion while they were about to marry when he was informed a) he was to break off his relationship with her or b) resign from the Army. What happened was over twenty years earlier she and a group of friends went back packing around the world, which they went in and out of Eastern Block Countries, some how she was never questioned about but placed on the watch list. Any way they were in America,where they lost money, broke and needed money to get to New York,they were offered employment. As my friend put it it did not matter the people and their family/friends were anti government in New Orleans( she called it the Red Quarters, I think it was a nickname ), but they offered safety, shelter, food for her group they worked there for some time before resuming travel to New York.
Last year her visa to America was declined due to her past.
Stealing a car,even in Australia people would not be employed as teachers even if charges did not go to court. I had a security check only ten years ago as I worked in a up market hotel it was at the time run by American Hotel Chain. They ask "Have you been arrested/charged by police even if it did not go to court". I had to go my boss and tell that I was fined for Jaywalking, Perth, Western Australia back in the 80's, he checked, sure enough it came up on my Police Check.... (slight Blush) I was running late where I had go, also wearing Head Phones( I blame the volume of David Bowie Music ) I did not hear him calling me to stop....... so three officers went into pursuit ........
I was informed if I had not admitted it my employment would have been under question.
I wonder how did the Step mother stay under the radar?
