Maybe it's the right thread to ask:
We will be flying from Europe to Central America in a few months.
On the flight there, we have s stop in Houston Texas.
Do I need to worry just about the transit?

If I would actually need to go the USA at the moment, I would have a completely empty smartphone and laptop.
But do I need to worry about the transit?

Edit: obviously I don't plan to do anything illegal, I'm just a tourist. But after all the stories, I'm getting a bit worried
