Wait, that's how they're actually dressed? They just look like random people. The fact that they don't get shot more speaks a lot about how well behaved the people they are kidnapping are.
They're also going after the population that are probably the unlikeliest to own firearms. That being said, if you're brown and not carrying a firearm and your "papers", you should probably change your habits. Fuck me, it's disgusting that this is the case in America.
