I would like to raise a couple of points here.
First of all,
there is a sticky thread on photographer's rights and laws in the
Gatherings, Events and Photo Trips forum here
https://www.pentaxforums.com/forums/gatherings-events-photo-trips/60281-photo...trictions.html
where I encourage people to post links to relevant sites for specific countries / Locations and the laws and rights of photographers.
Second:
With respect to photographing in public.
-As people have mentioned, this really does mean public property not just property open to the public, and there is a big difference.
-Also, the need for a release is that people have to be recognizable, and the release is generally for use of the photo for the purpose of profit. The example shown here where people are not positively recognizable does not need a release.
- News events do not require a release.
- it is also important to note, that if the subject is NOT on public property and you are, the subject must be reasonably visible from public property to photograph it. This means you can't encroach on doorways, climb fences etc to get the photo, that is invasion of privacy.
- you also need to consider copywrite in terms of use of images where trademarks or other protected images are visible in your image. This may include buildings, signs, or even re-staged images that someone else already took.
