Ok here is a brief reduction of the article.
Can I take pictures on the train station?
Yes, but there are rules to stick to and you must tell the station duty manager
Can I be arrested for harassment by taking a photograph of somebody?
Yes. For a harassment offence to have been committed the behaviour must have occurred on two separate occasions.
What should I do if the police stop me taking pictures?
The police in the UK can't stop you taking pictures.
Be polite, answer the questions and explain what you are doing. Remember they have heard every original excuse you can think of. If they search you you need to know the information contained on the following web site:
Police Stop And Search Powers etc.
Can I be arrested for invading someone's privacy?
No.
However the Press Complaints Commission has a policy which you should stick to if you want to stay out of bother
PCC Code of Practice
I like taking pictures of people - do I need to be worried by libel?
Yes - don't add a caption which says anything other than exactly what you have seen. "Man asleep on park bench" is probably ok, "Typical homeless drunk crashed on park bench" isn't.
If I am asked to wipe my memory card do I have to do it?
No. They are your pictures. If any MoP asks you to and starts to use threatening behaviour, call the police. The police have no right to delete them either.
Why can't I take pictures at Gigs?
The gig is a private place and it is up to them who can take pictures. If you do decide to take pictures anyway you could be treated as a trespasser
ab initio. This allows them to force you to leave.
Can someone stop me taking pictures of their house?
No, as long as you aren't trespassing when you take the picture - this includes leaning on their fence.
Can I take pictures of my children naked?
Yes. As long as they aren't indecent. unfortunately the definition of indecent is up for grabs. The photo marketing association issues guidelines to photo labs :-
1. Does the child appear to be under 19?
2. Is the child aware the photo is being taken (posed)
3. Are genitalia exposed?
4. Does the photograph have a gratuitously sexual implication?
5. Is it indecent by virtue of the context?
Can I take shots of my children playing Saturday league football?
Yes, if the teams are playing on public land and there are no by-laws to prevent it. Always check with the match referee and officials.
FA Guidelines
Why can't I take pictures of my child at school?
A school is a private place and it is up to the school who may or may not take pictures. There are child protection issues which should be respected - one of which makes it an offence for a carer to allow the identification and location of a child under care by the publication of a photograph.
There is more but largely covered well elsewhere.
I've been out and had problems with security people, and I know I should fit harder but when you're in a public place with families and you have someone "quoting" from the child protection act I just really didn't want to get into it. No amount of knowing your right can change peoples opinions on things. I was doing a job for a shopping center, wearing a security ID and some random old woman had a go at me saying I couldn't take photos of families eating their lunch. I had been asked to by the people who owned the building, and told her so. She kept ranting. I waved my badge, she kept ranting. People are hard to work with 
Hmm wait a minute though
