An old ritual has made things a little easier on the Breves: once a person in the family has been killed, there can not be vengeance from the family until the deceased's bloody shirt turns yellow in the hot Brazilian sun. (cinema-scene.com)
A man shoots a man (we see him on the floor with very bloody shirt), people outside the room hear the shot, scream and run or get down on the floor. (kids-in-mind.com)
And the bloody shirt is the enemy of both reasonable debate and good lawmaking. (firstthings.com)
