Sierra Leone Reflection

While I was reading "Sierra Leone is no Place to be Young," I wondered whether or not M.G. knowing all the prisoners he shot was a coincidence. Did the rebels stalk people before they kidnapped them to find out who was connected to them? I think that would be a possible strategy, since it would allow the rebels to break the kids and force them to fight more easily. I personally find the whole thing horribly wrong. If someone was heartless enough to kidnap kids for soldiers, I think they'd be heartless enough to find out who was conencted to them to harm them, too.
