Kerry is calling far Secretary Rumsfeld head for the Iraqi prison situation. Here is a direct quote from Senator Kerry about what he did in Vietnam.
There are all kinds of atrocities and I would have to say that, yes, yes, I committed the same kind of atrocities as thousands of other soldiers have committed in that I took part in shootings in free-fire zones. I conducted harassment and interdiction fire. I used 50-caliber machine guns which we were granted and ordered to use, which were our only weapon against people. I took part in search-and-destroy missions, in the burning of villages. All of this is contrary to the laws of warfare.
