I know they are focussed on immigrants but who do they target? Illegal immigrants? Because I have seen so many vids of them attacking people at work or in their homes that I wonder: are these people illegal immigrants? How does that work? How do they have jobs or a home without documents? Do they attack random people they suspect to be illegal?
