I don't know him and I know there are fake pictures and stories that do the rounds. This guy's profile just seemed really ordinary with nothing that whiffed of a troll. Now, he could be a bit of a bullshitter and over egging the pudding, but I got the sense he was just taken aback by it rather than saying, "OMG, this is outrageous, yada, yada," hysterics that you get with the fake ones. But no, I can't be sure.
I am seeing lots of tweets and posts related to people being detained at airports, but that there is official denial from authorities that it's happening, and scant mention in mainstream medai. I'm inclined to think that's actually happening, even though I can't verify it with, say a news article or government statement.
Like this sign - sure, could be fake, but given the multiple posts about similar situations and the consistent lying from the Trump administration, accounts from lawyers that court rulings are being ignored, etc. I'm inclined to think there's a lot of nasty shit going on.
