You don't have to see into their brain.
The US tends to use the reasonable person standard. If a reasonable person, with the information you have, would know that it's stolen, you knowingly possessed stolen goods.
Something that doesn't exist through legitimate channels, especially for a subject you portray yourself as knowledgeable of, is enough. You have to cast reasonable doubt with a plausible alternative explanation.
DOS2 working so well is a big part of why I bought BG3. I mostly play handheld (steamdeck, with a little bit of switch), so controller support is a huge factor for me.
