The necessity or benefit of open carry is debatable. I haven't looked up the law about disturbing the peace, so feel free to educate me. Clearly this law has not been used to stop people from open carrying. Maybe we need another law, or a revision of the open carry law. Going for strolls in peaceful public places with visible heavy firepower is more likely to do harm than good, and should be discouraged. Just the stress of having guns around is harmful for some people. Stress kills. More direct harm might well be done by someone else who is upset or afraid, and not the open carrier. I'm interested in harm reduction and public health.
