If you become of enough interest to the sort of people who will interview everybody who was any a party at a bar to try and identify who someone that's left the country gave their SIM to, you're probably well beyond fucked already.

Amateur opsec can help prevent you getting identified if you leave footprints in dragnet surveillance - like if you were at or near a protest. If you're planning on committing crimes serious enough to have "basic police work" set loose attempting to identify you individually? Good luck with that. I hope you're getting better advice than posts from randoms on internet forums.

True. Replace "crime" with "things that motivate the government to investigate you". They arent the same but overlap alot of course. In 2025 the non intersecting area got larger.

> "things that motivate the government to investigate you"

Yeah, as I wrote elsewhere in this discussion: "running a global drug cartel, or criticising Saudi Royal Families, or defending the rights of Palestinian children to not be bombed"
