“This is highly symbolic because it shows us how crime cannot kill ideas, how crime cannot stop the victorious march of a people; how crime, no matter how monstrous, cannot kill life, and how the life of each one of us does not belong to ourselves, but it belongs to everyone.  We are all part of something that is greater than we are, and that is Homeland, the people; our lives are part of the infinite and immortal life of the Cuban nation and of our revolutionary people.”
