I think you mean there is no reasonable legal expectation of privacy on a public street. I certainly expect that you will not follow me around videotaping me.
I don't know about the EU, but in the U.S. your statement is simply not true. Somebody absolutely can follow you around taking photos or videos, as long as you are in a public space and they can come up with any non-malicious excuse (i.e. it's an art project!).
Stalking laws vary state-to-state, but you generally have to prove it is specifically "for the purpose of harassing and intimidating".

Ah, I forgot that we are taking US data protection laws into account when an Austrian group files a complaint against an Irish subsidiary.
E.g. in Germany it is forbidden to take photos in public where people who did not agree to it are the main subject – you can still photograph buildings, scenes etc., just not individual people.
Your are in a public space, people can videotape you the same way they can look at you instead of everyone closing their eyes the moment put your feet on a side-walk.
Just look at all the photos you have taken, how many strangers are in them?
Sure, my point is that there is a technical legal argument and then there are social mores. We shouldn't let the legal argument start leading our values.
I invite you to actively start photographing or videotaping some strangers if you think such behavior is entirely within people's expectations.
That's why i said "videotape" not "videotape and sell/distribute it".
But even if you publish it (in Facebook for example) you are protected by some "fair game" clauses, just as you have the right to request that particular photo to be taken down. Either way nothing is absolute and as you said, it gets murky pretty fast.
But somehow if it's online, done by robots (no less creepy), and at the direction of the government, such laws don't apply.
