I served in the Army in Panama with a 100% native Indian named Kai. He very seldom drank but when he did, look out, he would literally go crazy. I remember being asleep in my bunk one night when he came back from town drunk. He kicked in the door of the taxi and when he got up to our floor he started beating the crap out of his friend who was fast asleep in the bunk next to Kai's......It was very ugly that night.
