Appalling...
...manner in which the people stopped get threatened and entrapped into committing arrestable offences by the police:
1. Photographer is stopped and questioned, being asked to give name, show permit, show the police the photos they have been taking, etc, just for the reason that they are taking photos. They may be challenged by "security people" or PCSOs.
2. There is no reasonable suspicion that they are engaged in terrorist activity, and so there is no reason for the stopped person to answer the questions. This is particularly the case if the person stopped them is a security person or a PCSO.
3. Person stopped objects and argues about it.
4. If it is not a policeman/policewomen who has stopped the person so far, the police are alerted, and we go back to step 1, with the police asking the questions this time round. If it is a policeman/policewoman, carry onto step 5.
5. For not complying with the request, stopped person is then threatened with being charged with a different offence (eg, obstruction) which would be easier to pin on them.
6. Stopped person has now been entrapped intop apparently committing this new offence which has resulted entirely from the police's unreasonable request to begin with.
It is useless expecting government officials to say something and the police to modify their behaviour: the police will just carry on until there are real consequences arising from entrapment activities and over-reaction to stopping people from taking photographs. Photographers will have to risk arrest, and having their DNA taken, etc, leading to failing future CRB checks and so on in order to try to mount successful legal challenges to all this that are not guaranteed to succeed unless there is specific protection under law to taking photos, which I don't see happening. The problem is compounded by the risk that, if journalists are at the forefront of this, then a "quick fix" will be carried out (as in the case of showing a journalist card when being asked to show a non-existent "permit") which will protect journalists and not other members of the public.
