@tsarstepan,
I'll tell you why he wasn't detected. He is an 11 year old boy with a firm purpose.
My two, when they were 11 or 12, did whatever they damned well pleased without fear of being caught because they had planned every move with the same precision as any other band of criminals.
I'm surprised the kid told anyone he was running away, my two would have disembarked, meandered through Italian customs and hitched a ride into town by saying they were meeting their father at the Colosseum.
