id just bring my phone. if the secret police are going to arrest or kill me, theyre going to do it either way, probably while im there.

if i bring a phone, i can at least document the secret police's actions, and make friends and get contact info for other people that are there.

security by obfuscation isnt particularly good, and its a state level threat.

there's a different absurdity with your child torture example - that youd be ok with children being tortured over phone usage. the bulletin and the people doing the kidnapping at torture are the problem, not the phone. there's a third option of stopping said torturers, and youll likely want your phone as one of the tools in doing so
