Actually, I live in Arizona, and my state cares A LOT. Its not only a horrible network of crime and slavery for profit, which costs millions every year to fight and to try to stop, but the people who are smuggled in to the country who aren't killed or deported end up living here illegally, which means they get to use all of our shit and don't have to pay for any of it. Arizona introduced a law last year called SB-1070 that allows cops to arrest anybody who can't show residency i.d. if stopped (most of these kidnapped kids cannot because they don't have any i.d., so the ones that police find would be deported instead of being raped and killed by their kidnappers). The federal government is now suing Arizona for being unconstitutional by passing the law, and much of the rest of the country has given us nothing but shit about it. People do care, and people are trying, but there are so many stupid people in America who just assume that the whole thing is just a way for racist cops to fuck with Mexicans that it has been a struggle to do it. Hundreds of those kids probably could have been saved from an awful fate if the cops were allowed to do their job without people marching in protest and suing us to repeal the law. But they do. People side with the criminals in this country and are too dumb to realize that they are even doing so.
But about Nigeria- Nigeria has always been one of the most corrupt places on earth. The government is in on most of this type of shit, therefor it won't end. Illegal diamond trade, human trafficking, and sea pirates have all been crimes in northern Africa that made world headlines in the last 10 years. It is just a big ass ghetto where dirty money is just as accepted as clean money, so criminals run the place.
but hey, 14 years for organized slavery operation is a steeper penalty than it sounds like, considering the average life expectancy in Nigeria is like 41.
