I'm not particularly thrilled with the way the government is reacting to WL etc., but I also recognize that it's rather difficult to tell apart real threats from unthreatening people who behave in many ways like the real threats would. Appelbaum can say he's not going to hurt anyone, but that's what any terrorist can say. His actions may be perfectly legal, but also probably constitute probable cause.
He hasn't been arrested, he's been searched. That is exactly what I'd expect the police to do in such cases. Your neighbors report a blood curdling scream from your house? The police come and check it out. It's not illegal to scream, but you'll still get asked a few questions.
When does it become harassment? We've probably crossed that line, but what's the solution? Once you're screened and land successfully, you're exempt from future screening? That'd be a pretty big security flaw.
Let's be honest here, the problem with wikileaks isn't the (nonexistent) threat to national security, it's their politics. These meatheads at the airport weren't concerned with national security, they were concerned with teaching this liberal pansy a lesson. Short-cop-syndrome writ large.
It sounds way more like harrassment than screening to me.
I'm a foreign citizen working in US on a visa, this has happened to me in the past - and I'm just here to work. I'm not suspected of doing anything illegal.
Immigration/Border Patrol in China is far, far more friendly than the US's. If Citizens don't like it and feel it is harassment then they should be campaigning to change it.
A US citizen re-entering America wouldn't be asked that question. The specific question also pertains to specific Nazi activity C1939-1945 rather than Nazi'ism in general.
As far as associating with a movement.. it's legal to be a Nazi if you want. There's a supreme court case for that, too.
