1. If Doyle's family background was on the 'shady' side (no one's ever been arrested, but a lot of their business has been somewhat questionable - just petty stuff, though) would he have been allowed to join the police? Doyle himself was never involved in any quasi-wrongdoing.
2. Does anyone know where the wealthy area of Liverpool is? I've been trying to find information on Liverpool but it's mostly just general stuff.
