As soon as I had taken a shot, PC Smith (40144) came out from the train station and asked to speak with me. She asked why I'd taken a photo of her van. I told her that it was parked in a disabled bay. She told me that she'd been called because a woman was self-harming on the station and that was the only place she could park...Police, Camera, Action... (Thanks, Scott Deathboy!)
I asked her why she wanted the photo to be deleted, she told me that "in the current climate" the police had been asked to stop people from taking photos of sensitive buildings and of the police.
That isn't true - and I told her so.
She was told by her superior that she could take down a description of me. I told her that asking to delete photos was silly because they can be easily undeleted. I also thanked her for not escalating the situation. I left. As I left, I allowed my phone to post the photo I'd taken to twitpic.
