CMV: Duels between two consenting adults should be legal

Basically what the title says, dueling should be legalized with certain parameters. Public dueling should be illegal due to risk for an innocent bystander to be hurt, but there should be a system in place where you can schedule a duel. Maybe have them take place in an indoor facility made to withstand a small pistol round, like the material used in indoor firing ranges. Seems to me like it would possibly cut down on innocent bystanders getting hit (like in a gang drive by scenario, if the two rivals are allowed to duel in a protected area that could prevent them from taking action in public).
