They're deporting them without trial. They don't even try to confirm they capture the right people. They've arrested several US citizens. Notice where this arrest occurred: at a courthouse. Why? Because this person was complying with the law and going through the immigration process.
What about masked men kidnapping random people, then sending them somewhere like a prison in El Salvador seems just to you? Do you remember this happening previously in your life?
I feel like they're arresting these people at courthouses so that it will instill fear in others of going through the legal process. Then they can deport many more immigrants and say "look, they didn't go to court, they're definitely illegal".
