I don’t see offshore leeks as a big deterrent, unfortunately.
The three big ICIJ leaks were not published as in dumped to the public. Only politicians, PEPs, obvious money launderers and some obvious other criminals were selected and exposed. (It’s only money laundering if you can proof the money comes from the proceedings of crime)
There are some criminal service industry leaks that are public, or have been public, yet it doesn’t appear more than a few individual have the motivation to follow trough in combing them. At least this is true for groups who would publish on their findings.
Fair enough. I go on the assumption that there will always be stuff we miss, and my customers do as well - especially given the time pressure that we are under to deliver. Even so, it's a given that some people will get away with these things. Interesting detail: over the years you'd expect something like this to pop up after the fact or in a subsequent DD if it goes on for long enough, but that has never happened. So maybe the number of missed cases is lower than what I would personally expect it to be (a factor of two would not surprise me).
