No citizen nor law abiding non citizen is affected. When you commit crimes, you “give up” your own liberty for the security of the public. That’s how all law works - when it is enforced properly, anyways.
You don't actually know whether these people are law-abiding or not, because there has been no due process. The government says they are in this gang, they say they aren't. Without due process we don't actually know if they got picked up for being in a gang, or just for having tattoos (which is what one of them alleges).
The law is blatantly absent if the executive explicitly states it can detain and deport any person it deems a threat without due process and without duty to notify anyone, let alone a court or judge.
It's literally the executive tyranny of a king and absence of balance of power in full action which led to the founding of the United States of America.
Even if you're a criminal, last I checked the law, properly enforced, grants you the right to an attorney to prevent exactly this: unchecked executive power.
