Getting an SSN card isn't necessarily trivial. You may understand that but what exactly do you know about it?
As for CrossCheck... can you do us a favor and actually watch and/or read the Greg Palast content on this? CrossCheck was aimed directly at purging people with the same name between states. Of course African Americans have similar last names because they bare the names of their lineage's slave masters' families. Can you see how utterly racist and appalling that is? The last name issue goes for Latinos too.
