On my way to catch the train I saw this at Cannon Street Station. I found it quite funny that the police guy was taking pictures with a big and heavy dSLR camera and external flash. Seemed quite odd to me and I could not resist taking a few pictures myself, even when it (maybe) meant breaking the law.
I am not writing this post from a jail cell so good thing the police here was busy dealing with real criminals ;).
If you are wondering what I am on about read here for more details.
