I agree that there is no expectation of privacy in public. This can quickly stampede into people taking pictures or video, in a public park or something that is now illegal to take, simply because of shit like this.
If you're in a publicly accessible space, or where I can see you from a publicity accessible space, there's no reasonable expectation of privacy.
This really isn't any different than him sitting there and watching from his window, it's just recorded.
Fucking Hamilton man.
