I'm in a mock trial in my class as king leopold and how can i defend myself once I get on the witness stand because everything i find is negative. And my defense team sucks. So any help because I want and need some extra credit. So I need good stuff to convince the jury that I am not guilty on any of the crimes that happened in Congo.

I'm afraid you're going to lose. About the only defense is that you're "helping" the poor natives.
