Lack of insight, hmmmmm, ain't we blowing this out of all proportion, it's a copper asking someone for their name and address. Not wanting to typecast you but I think your life experiences dictate how you react to this subject. I have worked in a service related industry and some of the people I have encountered over the years make me have no objection to the police asking me my name and address any time they want. Will even show them my drivers licence if they want to see it.
I agree entirely...those of us who work in the media...ie. Photographers, come across this almost every day. Yes, it probably clouds my view of the thing but still....
The law is:
1. They are entitled to ask you your address and name, if they wish to prove your identity and they feel it necessary to do so.
2. You don't HAVE to give them your name and address. If they still have reasonable grounds to arrest you (and the photographers positioning of the camera IS NOT reasonable grounds, unless he's blocking a road, a police officer from doing their job etc.) then they will do so. When you are booked in by the custody sergeant, THEN you must give your name and address, or they may search you/fingerprint etc. until they find out.
3. The police officer/PCSO was not correct in attempting to use s.44 in this instance. When questioned on the authorising officer/circumstances of the authorisation, they backed down. At any time when the officer realises that a search under terrorism legislation is false (ie. when they're made to look stupid, or when they realise there's no terrorist threat) then they revert to PACE powers...which they did.
Whether or not this person was being deliberately obstructive or difficult is entirely their decision, just as it's a joyrider's decision to run from the police or give themselves up when they wrap a car round a lamppost.
The point is, that legally the officers failed to act in the correct manner in this instance. What I still feel is unnecessary is people bleating about it on the internet afterwards. Guess what, it happens every day. It's probably happening right now.
You know when the burger jockey in McDonalds forgets to ask if you'd like to "go large"...that's failing to act in the correct manner...do you post a video on the internet afterwards?! No. You get on with it, possibly laughing or saying "oooh, look how stupid he was".
Won't somebody PLEASE think of the children?!
