Weathermen/SDS Links to John Kerry?

Colorado Conservative ^[1] notes today in history:

…an explosion rocked the headquarters of the U.S. State Department in Washington, D.C. No one was hurt, but the damage was extensive, impacting twenty offices on three separate floors. Hours later, another bomb was found at a military induction center in Oakland, California, and safely detonated. A domestic terrorist group called the Weather Underground claimed responsibility. Remember them?
Who were these extremists? The Weather Underground — originally called the Weathermen, taken from a line in a Bob Dylan song — was a small, violent offshoot of the Students for a Democratic Society (SDS), created in the turbulent ’60s to promote social change.

I was curious about links between this group and John F’ing Kerry.

Here’s the search I started ^[2].

Here’s another at Google ^[3]

Seems a lot to look through.

Lots of links match the searches, but I have to plow through each one to come up with anthing of use. Perhaps some of you would be interested in helping plow through the match list
