Good question. Why is he in jail? 'd love to know if El Salvador knows something we don't. Have you wondered why he is in his own country, and they are keeping him in prison? As far as the US is concerned, he could be at home with his mom. Why has El Salvador drawn a line in the sand to keep him in prison when it's only a financial drain on them to do so?
No. Not anyone. It's the Alien Enemies Act. I guess we've been authoritarian since just after we were founded.
The Alien Enemies Act is a law.
Looks like they did. El Salvador. My understanding is that he was accused of being in a gang that has been deemed a terrorist group, and is part of the AEA roundup. Two judges agreed. He had his chance at that time to show that he's not, and didn't. If he had self-deported when given multiple opportunities, this would be a non-issue.
