Kerrey's squad member has testified that those people were ordered out of their hootches into the center of the village by Kerrey and his men after the squad entered the village. What happened next is open to debate, but the fact that the villagers all ended up dead is not. And Kerrey's claim of longrange fire is clearly false.
It doesn't matter. She is self-admitted VC. The whole village was VC. They weren't "collaborators," they were combatants. They weren't innocent, they were an actual fighting force arrayed against their fellow citizens of the RSVN to install a communist government.
I know a little about what the VC were and were not. My wife is Vietnamese.
