GIANNO CALDWELL: Four years after my brother’s murder, I’m marching for justice

Four years ago, I got the call no family should ever receive. My innocent teenage brother, Christian had been shot and killed on the streets of Chicago . He was just a kid, full of promise, full of life. Gone. This Saturday, I am going back. Not to mourn. To march. Chicago is the shining example of how soft-on-crime policies devastate families across our nation. It is the epicenter of a political failure so profound and so deliberate that its consequences have spread to cities all across America
