Guess he couldn’t resist. To go there you have to pass at first immigration control - you are asked then if you were a Nazi and/or a terrorist and if you are planning to immigrate illegally.
This sends the first message to the tourist - “we dare you to try and be funny on us”.
Next encounter in the pub - even if you look like 72 - all white hair and a walking stick - you are politely asked to show your ID if you want to enter - for AGE VERIFICATION.
That also sends a message - we know you are of legal age but we can’t be allowed to think on our own in this country... Double Dare !
I guess Disneys guards just tripped the last fuse. Allthough it WAS understandable that they felt threatened to be bombed by a normal family father (wouldn’t they Milley ?).
After they asked him in a serious tone to repeat what he’d said, he should have gotten a clue that they weren’t going to handle it as a joke. Most likely if he’d said at that point “I’m sorry, I was joking but I guess it’s not very funny; feel free to search my bag, there’s nothing unusual in there,” they’d have let it drop. Honestly, in a huge crowd situation, in a location which is clearly a likely target for Islamic terrorists, somebody saying anything about a “bomb” is apt to panic some nervous person into screaming “Oh my God! There’s a BOMB!”, and starting a dangerous stampede. I don’t blame Disney and the police for taking it seriously. A panicking crowd can be just as deadly as a real bomb. Try yelling “Fire!” in a crowded theater, and you’ll get hauled away by police just as fast, for the same reason.
