No Bull

Ok so this is a picture of a cow. Whoopee. Yes but this is zone one in London. Ah ha a little unusual wouldn't you say. I started taking pictures of said cow and chatting to it. Yes also a little odd but it's a cow in London, zone one.
I'm taking pictures when a security guard came out and told me this is not allowed. A group of young men nearby came to my aid and said: Its a cow in the centre of London of course you are going to take pictures and by the way where's the law that says she can't take a picture of a cow. The guard left.
So here is a picture of a cow.
