As much as the scenarios can be rare, there is an undeniable sense of everything hanging by a thin thread when traveling around the USA, which I've only experienced in Latin American countries in all my trips.

Giving that I'm originally from Brazil even though with Swedish citizenship, I won't be traveling to the USA anytime in the near future. I have no idea what could happen, might be a completely rare occurrence to be profiled at the border, jailed for no cause, etc., but there's nothing in the USA worth enough to make me even more paranoid at crossing its borders. It's more like the straw that finally broke the camel's back, it's been brewing for a while, I've been stopped by CBP for holding both a B-1/B-2 visa on my Brazilian passport as well as an ESTA on my Swedish one, I do not want the potential issues that another interrogation by CBP at present times could create, like being sent to some jail for 20 days instead of just being refused entry and put on a plane to get back to the EU.
