Young men, of course, often get in conflicts where they are threatening one another: that is, where both of them are trying to scare the other with "imminent great bodily harm." Florida's law may allow one of those chest-bumping young men, without consequence, to end the mutual dispute by shooting the other dead on the street. When it is over, the only witness may be the shooter, and his version of events will presumptively control. There is no morality in this rule.
