Semi-automatic weapons have no socially redeeming purpose.

I have always believed that I could help change the world, because I have been lucky to have adults around me who did.

You have to have a fundamental change in the culture of policing, and who is the police person. How do they change? How do you learn from England and the other places, or Australia? In England, they don't carry guns on the whole. It's a different kind of mentality that does not demonize, and it's justified on race and income and class.

You just need to be a flea against injustice. Enough committed fleas biting strategically can make even the biggest dog uncomfortable and transform even the biggest nation.

I was taught that the world had a lot of problems; that I could struggle and change them; that intellectual and material gifts brought the privilege and responsibility of sharing with others less fortunate; and that service is the rent each of us pays for living - the very purpose of life and not something you do in your spare time or after you have reached your personal goals.

In my generation, we learned how to be leaders by being exposed to and involved with adults who empowered us and gave us a sense that we could choose things. We've let down the generations coming behind us and we are trying to re- establish that connection.

People want to pick the leader, and we are obsessed with celebrity and whoever is on the cover of this or that.
