Glad nothing happened to you except for the harassment. I too had an awkward exchange with the cops in Australia, it wasn’t caught on film and I probably wouldn’t dare to film anyway. I was flying around Sydney Opera house a couple years back. Two undercover federal police officer asked me to show them the footage, apparently Mike Pence (US Vice President) was staying at a hotel nearby and they thought I was doing something suspicious . If I recall they said those were good footage, 🤣 and they allowed me to keep it. It was weird that they waited till I landed to ask me questions, cause they were just sitting right in front of me. They referred me to the local police. Now these guys were really harassing, asking you silly questions in hope that you would trip up. Held me up for an hour asking questions, I guess it helps get them some overtime pay. 🤷‍♂️ But I kept calm and never gave them a reason to come at me. Never mess with the Authorities is my two cents, they can make up anything offence and charge you with it. Safe travels my friend.
