Taking a photo of a bus stop in a village in Kharkiv Oblast, Ukraine. Photography in oblasts bordering Russia or near the frontlines is banned. A military dude saw me, we had a little chat and he decided I was highly suspicious. He called the police and I had to spent a few hours being interrogated at the local police station.
They eventually let me go after stumbling upon monkey putin images while searching through my phone.
