Yeah, but there is a dark number of cases that don't make it to the media, e.g. I just read by a guy who had a 15k$ cruise ship trip booked from the US and was rejected at the border because they found his flight stop "unusual" he came from Australia and had a stopover in Asia because that was the cheapest flight. He wasn't imprisoned without any legal process, but the number of people rejected without cause ought to be much higher than the number of people who will be detained.
I grew up in a tourism country and the number one rule of tourism is that if you want people to come hospitality goes a long way. A mad-king-leader calling them freeloaders and quoting Napoleon with "He who saves his country, violates no law" and a cult like followership doesn't exactly instill confidence that your rights will be respected when you go there.
The current administration seems to be downright hostile to everybody who isn't a US citizen even if we'd just come to spend our money in the US. Pair that with a lack of basic oversight over your cops/TSA-agents/whatever and suddenly the US just isn't as attractive any more.
Don't get me wrong, I find the US fascinating, but given I am in the middle of Europe, I have many destinations with a friendlier atmosphere and a more reliable political leadership to chose from.
