I was "thrown" in the cell of Wellington Arch having been caught taking photographs of a model in lingerie on Marble Arch with Marble Arch in the background of the shot.
I wasn't fined or prosecuted because I was already
known to the necessary authorities...my day in the cell was more taking the piss because I took the piss.
As it happens I had been a house guest of the controller of Crown Estate Photography permits a year or two before & was also often employed as a London location scout for many.
I liked my job. I was good at it. I got paid a lot of money for doing it.
blahblahblahblah
If you take shots you intend or potentially consider maybe for publication there are considerations to be made, permits to request & permissions to be granted etc etc.
Some call it "professionalism".
As I have alluded already I regard Paul Russell as a professional photographer, of sorts.
Obviously you must regard him as something else.
What is the point you are trying to make?
