It's ok to take a picture of the street out of your front window

It's not ok to take a picture of everyone that walks in front of your house, timestamped and on top of that you search their picture on Facebook (supposing you could do that) and keep all that info forever

Why not? It's certainly not obvious why this is the case.

I guess that's a fair question. Two reasons come to mind:

1. If the by-passers where to discover what you've done they might feel violated. This is why there are laws against stalking. Thus in this example it would be all about intent.

2. What if your database leaks? Have you considered that event, the probability of it happening, and the impact? How can you minimize the risk? Is it encrypted? How long do you need to store it for? Can it be anonymized? Do you even need to look up name? Is the potential privacy intrusion proportional to the purpose of collecting the data?

To be GDPR-compliant you must have answered all those questions and documented it.
