This is one of the biggest reasons to never go to usa for a vacation. USA is the most corrupt country in the world. It doesn't matter if they have fourth ammendment and any other laws that protect people when those laws are not followed.
Read the law and ask a lawyer and they will say you have nothing to worry about, the laws protect you. Then you read the experiences by travelers and incredibly many people are saying their rights have been violated.
Yes other countries do this too but usa is the worst of them all. And it's also usa who started with this corrupt scheme which inspired some other countries to do the same.
Bullshit.
Some hard stats on US CBP traveler screening from
https://www.cbp.gov/travel/cbp-search-authority/border-search-electronic-devices emphasis is mine:
Of the 420 million travelers CBP processed at ports of entry in FY 2024, 12,660,784 (3%) travelers were referred for a secondary inspection.
A border search of electronics is not a required action during a secondary inspection. In fact, CBP only conducted border searches of the electronic devices of 47,047 travelers in FY 2024, representing approximately 0.3% of secondary inspections and less than 0.01% of all arriving international travelers encountered at ports of entry.
Of the 47,047 border searches of electronic devices encountered at port of entry, 42,725 (90%) were basic searches in which the devices were not connected to external equipment to review, copy and/or analyze its contents.
Given that - I for one have zero concerns crossing US borders. Of course regarding
other countries could well be a different story... It all depends on their own laws.
As a Frequent Traveller with over 10 million air-miles to my record from when I worked as an industrial laser Field Engineer for over 48 years flying all over the US and the world, at least 1/2 of the miles were from international travel. In all those years only 2x did I have to go through any sort of secondary screening in ANY country and none involved searches of my computer or phone. One country was China and the other oddly enough was Canada - both were only interested in the contents of my service tools kit and details of my work VISA.
