Quote context

[...]

- Who says we have a claim to register?

- Whatever you say or don't say, tomorrow, I start to dig for gold here.

- I know very well you guys can bump me off any minute you wish, but that's a risk worth running considering the stakes.

- Let's lay all our cards on the table.

- As I see it, you guys have got to do one of 3 things... Kill me, run me off, or take me in with you as a partner.

- Let's consider the first.

- Another guy may come along tomorrow, maybe a dozen other guys.

- You start bumping people off, just how far are you prepared to go with it? Ask yourselves that.

- Also, don't forget, the one actually to do the bumping off would forever be in the power of the other two.

- The only safe way would be for all 3 of you to drag out your cannons and bang away at the same instant like a firing squad.
