The OP was sitting on a bench, in plain view, not even moving around. I don't think that in any way constitutes stalking. Take out the word "stalk" and I agree with the statement.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
