If I was a powerful speaker, I would use my ability of touching people, to make criminals reflect. I thought about how I want the world to be before thinking about this question, and my answer was "a peaceful world". I hope the world can be peaceful. So, we should decrease the crimes. I would send the messages to change criminals' mind and heal their hearts during my powerful speech. then make them follow. So that they can reflect themselves and over again to live. They can't undo the past, but they can make changes in future. I should become a powerful speaker. And to become a powerful speaker, I should practice a lot and remember the techniques make speech good. I'll work hard !!
