Going back 25 years if someone took undeclared cash out of the country (my country) their phone would be searched 100%.Then, he should be dealt with on that issue, no problem.
Additionally, it’s seizure and upto £5000 in fines. However, I didn’t know it was leaving, too.
Given that, he should have known better. The use of the Terroridm Act and searching his phone? Fuck that!
And, don’t think I don’t know the US border is a nightmare, too.
I cant imagine it would have been different in the UK.
