The Guard at the Binh Thuy Bridge

A guard in a bridge is order to shoot everything that passes by, he see a women in a small boats get closer, he aim his gun at her and in a second react to what his doing. He drops his gun and can't believe what his doing he was about to shoot an innocent lady for no reason. I think a man behind a gun becomes a totally different person as if the power of a gun seem to take over people making them fell invincible. I dont know how we can decided in a split of a second shoot someone with out feeling guilty.
