Annobel...who protected the miners from these imported, unnumbered police.
In the past I have demonstrated with my face exposed but now it would depend on the issue.
Special Branch always kept records of protesters but they had to expose themselves.....I was once on a picket line where the real news reporters pointed out a couple of men with cameras who where not reporters. Now with the advent of cctv, email tracking etc they can monitor any of us and arrest us under the draconion terrorist laws. Recently a lady in Bridlington was arrested under the terrorist laws because, in a conversation on facebook about the fact that no person from Bridlington actually carried the torch in that town, she jokingly suggested that she would take a water pistol and squirt it at the flame.
Times have changed. We may not be an open police state yet but the system is in place should the government decide we should be.
