"As we�ve covered before, courts have ruled time and again that police can�t force citizens to stop taking photographs of them in public so long as you don�t interfere with their work. That doesn�t stop cops from ordering people to put their cameras away, and didn�t prevent on sheriff�s deputy in Washington state from making multiple empty threats of arrest against a Seattle news photographer who took pics of a police action in public. But after an investigation by the sheriff�s office, that deputy has been dismissed for abusing his authority."

And down the story a bit -

In 2011, the U.S. Court of Appeals for the First Circuit ruled in Glik v. Cunniffe that private citizens have the right to record public officials, including police, in a public place.

The court held that the First Amendment�s proscription on laws �abridging the freedom of speech, or of the press� encompasses a range of conduct related to the gathering and dissemination of information.�

I'm thinking that the big reason for the firing was that he fudged up his story to his supervisors.  They can't have that happening, ever.  But still, it's a win.

1) UK not USA.

USA - They can't stop you, or prevent photos or video in a public place and they can't make you erase things or take your equipment or data.

2) How hard is it to give your name and address to the officers and be allowed to walk away?

I mean, when I'm stopped, I offer the information, and I've never had a problem. That includes airports, trains, power plants, industrial and many others. They are just asking "who are you?" and you can be sure it goes into their notebook.

I held my right not to say a word to this people who imagine we live in police world and show id only and only if they respected full part of their legal procedure(introduced them self properly with a badge or card in some countries , gave me the reason why they stopped me and why they need my info.

In the meantime i record everything on the phone for my and their protection with live streaming on internet just in case they get an idea to erase the truth and if arrest me for reason they imagine its legal, they will have to stand up and justify that decision in front of a judge with full responsibility for their act just as I have to do for mine .

Never get on your knees and reject your rights and dignity  in front of an public servant who is here to make your life easier and not to invent problems just to get some money out of you for the system.

And that goes legally for any country in the world because most are co-signers of human rights declaration which is highest legal act of them all and all laws should serve the declaration.
