Is it a visual search, or do they make a copy of all your data?

This case is about a “visual search” as in CBP agent going through your photos. Not forensic tools copying / analyzing all the data

It probably depends how pissed off you made the officer at the border if he just wants to thumb through some recent text messages and photos to see if you're doing Crimes or if they're gonna go take it to the Cellebrite UFED in the backroom and dump it out.

In other words... whom (or what) was perceived to have pissed in the CBP officer's Wheaties this morning? We'll never know what grudges he holds to make his decision.
