As an Asian Photographer . . .
As usual I think the Country is going PC nuts. I'm always out and about with my camera. Admitidly I have not yet been stopped by the the police for taking photographs in public places.
I am well aware of my rights and would promptly remind any mis-guided police officer of the laws around my photographic rights and question why I was being stopped/searched.
However, I think the "heavy handed" approach is far better then the soft approach that seems to be what this article is describing. As mis-guided and ignorant as the many members of the police force appear to be regarding their "powers", the approach they take could ultimately catch exactly those people that they are targeting. Although some of us may have to bear the inconvenience of being stopped as well.
I say let them carry on. We just need to be aware of our rights in the instance that we are incorrectly targeted. I know I am making these comments prior to any potential stop and search that I may have to endure (at that point maybe my mind may be changed!)
