looking for footage of tet execution also

You can find a copy of the still photo at http://www.treefort.org/~cbdoten/rvntanks/080-4450.htm

I was wondering if anyone knew where I could find the footage. If you know of anywhere please email me at broy703@hotmail.com. I know the executioner is named General Nguyen Ngoc Loan and the executionee is Bei Lop. The photographer was Eddie Adams.

Thanks, Brian
