Horiuchi was interviewed shortly after he killed Vicki Weaver. Somehow some very enterprising news team (remember those?) tracked him down and asked him about the rules of engagement, and whether they justified his action. He replied, angrily, that the ROE was just "semantics".
That interview apparently vanished- I saw it once, on TV, and apparently it never played again.
If anyone wants some detail on this, Weavers attorney, Gerry Spence, wrote a interesting book on the case.
Randy Weaver just wanted to be left alone. The Feds tried to entrap him, blackmail him, spied on him, and killed his dog, his son, his wife, and badly wounded his best friend.
