Walk the Blue Line

America's cops are our eyes. Our ears. Our protectors. Those who wear a badge do their best to help people. These men and women serve their communities. They service their country-- even at the risk of their own lives. Here patrol officers, K9 handlers, sheriffs and detectives reveal what it's really like to wear the uniform. And to carry the weight of the responsibility they've been given. This is the job. -- adapted from jacket
