50 years later, echoes of 1968 resonate in US

US troops in a never-ending war. Students marching in the streets. Women demanding respect. Black athletes protesting for racial justice. Political upheaval.

Today's headlines?

Yes.

But they also could be from 50 years ago -- 1968 was a year so eventful that it's become known as "The Year That Changed America."

"Assassinations, riots, rebellions, protests, disorder and chaos -- 1968 was a year of really extraordinary shocks, shocks that I think still reverberate through today," said David Farber, a history professor at the University of Kansas.
