Yes they have. Are you stating for a fact that's the case here?
No, I'm stating that the confessions and convictions don't prove your claim that Coleman's actions were effective or deserving of imitation.
Prove my claim? The confessions and convictions are real. What would dispute "my claim" is some kind of proof from you that these people were innocent.
Without that, the confessions and convictions indicate to me that Coleman's actions were effective or deserving of imitation.
