I guess I'm selective. When IMO the risks of not carrying outweigh the risks of carrying, I do so. Otherwise, I opt for the knife. It is much harder to get thrown in jail with a knife, especially in Indiana where knife laws are very lenient.
And how do you predict that? Can you predict when you will trip on a crack in the sidewalk and fall and break an arm?
I carry because there are many in the world that have no regard for human life.
