Am I missing something here? I'm not getting the outrage. The guy overstayed his visa, got caught, and is being deported, what's the problem exactly? Everyone knows the risks involved in overstaying a visa, everyone knows America's ridiculous stance on pot convictions, his getting married was his choice in spite of all of that. If he was ignorant of all of this, that's his lookout, it was his job to research it before travelling.
What's going on at the American borders is disgusting, their refusal to comply with international agreements on asylum is infuriating, the Nazification of Border Patrol and ICE is absolutely terrifying, but isn't this basically open and shut? You take the risk, and if you get caught you put your hands up and accept it. And you ask Ireland to take in your wife and kids, and we almost certainly say yes.
I have to be missing something. What am I missing?
