Deadly shootouts are probably far less likely when it’s realized that both people are armed. Face it, criminals and others inclined to violence are far more likely to avoid a target that may well shoot back, or even shoot first.
Looting during blackouts would go down for the same reason: If you know for a certainty that the home or business you’re breaking into has one or more armed people inside it, you’re probably not going to give it a try.
I would suggest that the guy who goes bats and starts shooting up his workplace be shot quickly by one of his co-workers. Taht makes a lot more sense to me than making sure everyone in the workplace is unarmed and therefore a guaranteed victim until such time as the “authorities” can get a clear shot or the guy gets bored and offs himself. The comparative body count is much lower.
You can’t eliminate violent insanity, you can limit the numbers of victims.
As to the judges, that’s why I recommend there be a volunteer core. Ideally, both sides would pick three judges from the list. If there’s a match, that’s who hears the case. If not, they pick again but don’t use any of the names from their first attempt.
I don’t want to hijack this thread and turn it into SDMB’s 917 kabillionth gun control debate. Can we just please stipulate that a significant faction of anarcho-capitalists believe in universal armament? The merits and drawbacks of that stance have been argued ad nauseum in other threads, and I’d like to see this one get back to something resembling the OP.
