I've never liked Farah but you can't really blame him.
Yes, he was an illegal immigrant and concealed the fact. Even though he was an infant when he was trafficked and not responsible for his illegal act.
But I have to say that in his shoes I would have done the same.
If the choice was
1. Own up and get sent home to the hell hole that is Somalia or
2. Keep my trap shut and stay here.
It would have been number 2, all day long.
