Nothing we do in this great capital can change the fact that factories or information can flash across the world, that people can move money around in the blink of an eye...

Music can give you your dreams. It will teach you hard work, it will break your heart and make you so happy, you can't stand it. . . .I don't think I'd have been president if it hadn't been for music.

Tonight, I propose a 21st Century Crime Bill to deploy the latest technologies and tactics to make our communities even safer.
