Let's see here. I don't know the details of this case, but I don't think this should automatically be thrown out so please allow me to play devil's advocate here.
First off, everyone, remember that crossing the border "illegally" is
not, in itself, a crime. You don't get arrested for it, you don't go to jail for it. When you get caught, you get taken back across the border by immigration agents that act in their function as customs enforcement officials, not officers of the law.
Regardless, committing a crime does not automatically eliminate someone's civil rights anyway. Due process still exists, convicted criminals can still successfully sue police officers for mistreatment. What these people were doing on the guy's property is entirely irrelevant to the case at hand.
Also, this may be arguable by some, but an American isn't entitled to basic human rights because they're an American, but because they are a
human, and in this amazing country we aim to treat all humans with basic rights given to them by God. An illegal alien doesn't have all their rights forfeit just by not being an American.
Having made that preface, the facts of the case definitely warrant some sort of action. Sixteen people are trespassing, and are caught by the landowner- there's nothing wrong with that. Threatening to shoot them, making acts of intimidation and violence, holding them extralegally- these are valid points of legal contention.
I'm not saying the sixteen are in the right at all. But I see no reason why extraneous factors about this case don't warrant a trial. Yes, the damages they seek are really excessive- but such is the legal system.
That's really all that needs saying, I think.
PS- Good to see you back, States
