I remember seeing this video a while back. what I read about it, was that the gangs over there use these little foreign kids as pickpockets. they force them to do it, because of how the cops deal with foreigners over there. they won't get in as much trouble as a regular chinese person would, but they also get treated like shit by the locals. it's a fucked up situation. on the one hand the kid is too small to even know what he's doing really and he's being forced to by older kids. on the other. stealing someone's wallet that is struggling to get by as it is. that prevents them from eating and feeding their family. so I can understand the frustration.
