That's because lots of states require permission to exercise a constitutional right. If more people were armed this shit wouldn't happen at all, or would be stopped quickly.
And it happens more than you know... but it doesn't fit the media narrative, so they do not report it.

This happened in MAINE which allows for Concealed Carry,
The RAND Corporation, a nonprofit, nonpartisan research and policy organization, analyzed firearm ownership in 2020 and created national and state-level estimates. It found that approximately 48% of adults in Maine live in households that own at least one gun
Effective October 15, 2015, Public Law 2015, Chapter 327 (LD 652), “An Act To Authorize the Carrying of Concealed Handguns without a Permit,” allows a person who is not otherwise prohibited from possessing a firearm to carry a concealed handgun in the State of Maine without a permit. This law also authorizes a person to possess a loaded pistol or revolver while in a motor vehicle, trailer or other vehicle being hauled by a motor vehicle.
Concealed carry without a permit is limited to people who are 21 or older, with the following exception: If a person is 18 years of age or older, and is on active duty in the Armed Forces of the United States or the National Guard, or has been honorably discharged from the Armed Forces or the National Guard, and is not otherwise prohibited from carrying a firearm, the person may carry a concealed handgun. A person who is 18-20 years old and without the referenced military qualifications must have a permit to carry concealed. The law applies to both residents of Maine and non-residents.
The law does not otherwise change where a person may carry or who may possess a firearm.
SO, almost 50% of the states adults have Guns, AND are allowed to Carry them... guess none of those people with guns are "good guys"
