It is not illegal to work without being a citizen. It is illegal to knowingly hire non-citizens. I've read a few articles on this raid and it seems although they used "identity theft allegations" to start, nobody was arrested in relation to those allegations.
So they raided a company under false pretenses, arrested hard workers, let anybody who actually committed a crime off without even a warning, and now the people arrested are going to be removed from the country to a "shit hole country" that they probably have never been to without a trial for the non-violent crime of not going through an unnecessarily restrictive, slow immigration process. This is not integrity. This is human trafficking.
I know it sounds like I'm talking out of both sides of my mouth here trying to say these people may have committed a non-violent crime but the real criminals are those people who committed a non-violent crime, but it's pretty obvious to me that ICE did not improve America with these actions. I have doubts that it opened job positions that'll actually be filled because statistically speaking they were probably paying the immigrants next to nothing and Americans have more pride than to work for that amount, hence why immigrants were hired to begin with. The company failed but the people are punished.
