In chapter 4 chapter there was an opening in my opinion to take the black water money
The gang at chapter 4 was already starting slip up
Sean dead they shot up Rhodes and go south
It does not take a rocket scientist to know that the gang was near saint Denis
As no gang would be crazy enough to kill Bronte and the failed trolley stations heist the pinkertons where already alerted and started to make a trap
But this was there opening to take the black water money
The pinkertons have poured everything into saint Denis to finaly catch dutch
So this would be the perfect time to get the black water money while all the majority of pinkertons resources are in saint Denis
If I was dutch I would continue would Hosea idea of setting a distraction to make the pinkertons think the bank robbery was starting
The plan is to send Hosea, Arthur,Javier and Lenny to black water
While dutch and the others set up the distraction and maybe even a fake bank robbery to pull pinkertons in
