The Tombstone gun ban was only for saloons and casinos, and anywhere else.
Effective April 19, 1881, Tombstone City Ordinance Number 9 states:
"To Provide against Carrying of Deadly Weapons
Section 1. It is hereby declared unlawful to carry in the hand or upon the person or otherwise any deadly weapon within the limits of said city of Tombstone, without first obtaining a permit in writing.
Section 2: This prohibition does not extend to persons immediately leaving or entering the city, who, with good faith, and within reasonable time are proceeding to deposit, or take from the place of deposit such deadly weapon.
Section 3: All fire-arms of every description, and bowie knives and dirks, are included within the prohibition of this ordinance."
Firearm permissiveness remains a problem, and most Americans support reasonable restrictions and law enforcement's duty to enforce them.
I would contend that firearm permissiveness has only been a problem when there is government corruption and the use of violence against the government is warranted, such as the original American Revolution, Shay's Rebellion, the Whiskey Rebellions, Bacon's Rebellion, Native Americans attempting to uphold treaties broken by the US government, etc.
The authority for government comes from the inherent authority of individuals to defend their rights, that they can then delegate to a government charged with their collective defense. Legislation like Prohibition, the War on Drugs, 3 strikes, asset forfeiture, illegal foreign wars, no-knock warrants, etc., then are NOT legal and do justify armed rebellion from this government corruption. When people are not harming others with alcohol, drugs, etc. then government has no legal authority.
When it comes to random violence, average people are not a problem. They are inherently social and have instincts against murder. But police do not. They not only have had their instinctive prohibitions against murder neutralized by military training, but encouraged to be exceptionally violent by horrendous and totally illegal police training and policies. Such as pointing loaded weapons at unarmed and innocent people, deliberately trying to kill fleeing suspects who are no immediate risk, etc.
Are there too many murders? Sure, but we know the causes of crime are poverty, injustice, lack of opportunity, inaccessible health care, etc. Access to weapons is not and never can be a cause of crime or violence. That is because just like the accessibility of illegal drugs, illegal weapons will ALWAYS be available. The additional minor penalty for violating gun control laws will never deter anyone who already intends to risk murder penalties.
The main threats we face in society does NOT come from average people even if they all had machineguns. It is not even from career criminals, because they are a small minority, not well organized, and only out for temporary profits.
The real threat to all normal people is and always will come from organized political corruption. We are always potentially on the cusp of 1933 Germany, and can easily descend down into that road of a total draconian dictatorship at any time. Things like murdering 3 million innocent Vietnamese, lying about WMD in Iraq and murdering half a million innocent Iraqis, etc., should be proof of how all governments are always a corrupt threat.
