I was shooting video of a car park exit last year. (I was trying to prove to the shopping centre owners that it was dangerous.) Mundane footage. Some lady drives out in her car and sees me. Winds the window down and starts on the you don't have the right to film me carry-on.
I politely informed her that, I'm sorry, but I do. She's in public. That's the law (in Australia).
Another fun one, while I'm here. C. 2010, we're shooting a music video in central Melbourne. We're on the public pavement. There's a bank ATM waaaay in the background. Bank security come out. Sorry mate, you can't film here.
We told them, we can. We're on public land. So they call the cops. We politely wait for the cops. The cops turn up.
"This sounded much more interesting on the radio", the cop says. They left us alone to finish the shoot.
