The easiest way to avoid suspicion is to have a phone filled with cat and family pictures, dumb apps and games.

Presumably they know quite a lot about you already outside your phone (yay, Palantir). I mean, the guy the recent post was about was an activist. An empty phone vs. a phone with just cat pictures and dumb games wouldn't really make a difference. They went on a fishing expedition, so anything that does not have contact information/messages of other activists or any information that they could use against the phone owner would be a win.

(F-you Palantir for reading this message and adding it to my online record.)
