One thing that sticks out to me is when they talk about Cohen - Trump's former lawyer and 'fixer'.
I wish I had a fixer. It normally seems to be dodgy rich guys who have them, for example Richard Desmond the porn baron who owned The Express at one point, and Channel 5 I think too, had a guy described as a fixer. His job - in as far as it was reported - seemed to involve getting rid of witnesses who might testify against Desmond using a combination of carrot (in the form of brown envelopes stuffed with large sums of money) and stick (threats) to persuade them to leave the country.
The 'as far as reported' but seems relevant though, cos of course they only make the news when their boss is in the news for something bad. However I do suspect most of what they do does involve sailing quite close to the wind legally. Rock up in a new city and want some drugs but you don't have a connection, no problem, get your fixer on it. Annoying journalist sniffing around your affairs looking to write a hit piece, say to your fixer "Make this go away, don't tell me any details" and so on. I can imagine you become quite reliant on such a person, if they are at your beck and call 24 hours a day (as I suppose the best ones are) and can smooth out any problem big or small with minimum fuss then they could quickly become your most trusted and vital employees.
I wonder how people fall into such a role, and how does one obtain a good fixer if you don't have one? Maybe there are coded job adverts you can place in certain places which will be understood as requesting this type of person, or are they more likely to be someone who came up with the big guy, a shadowy part of his inner circle who knows where the bodies are buried and is trusted implicitly, bound to him by shared crimes.
I'm really just thinking out loud now, but I suppose ultimately it's another one of these things that I find fascinating in that it's totally alien to me, completely removed from my world, and yet for a certain type of person or in some spheres it's a totally expected and understood part of the way business is done
