Got it in one!

Most liberals think banning guns will prevent gun violence. However making gun control legislations does not stop gun violence or access to guns, Mr. Phillip Luty proved anyone has access to firearms by making the 9mm luty from spare parts in a house garage, as well as bullets from scratch. Criminals also don't follow laws, so why would a criminal listen to "common sense" gun control legislations. "If violent crime is to be curbed, it is only the intended victim who can do it. The felon does not fear the police, and he fears neither judge nor jury. Therefore what he must be taught to fear is his victim" (Jeff Cooper). Criminals don't fear being prosecuted, otherwise they would not be criminals at all. In fact when the criminal opens fire on innocent people a law isn't going to stop them, but a well placed bullet will. On December 29 in 2019 a criminal attempted to shoot a church congregation in Texas. "When a man pulled a shotgun out from under a long coat and started shooting into a church congregation near Fort Worth, Texas, last winter, Jack Wilson didn't hesitate. Within seconds, the volunteer security guard unholstered his weapon and returned fire. With one shot, Wilson killed the 43-year-old gunman and then kicked the shotgun away. Keith Thomas Kinnunen had already shot two congregants, who died. But there were more than 250 people in the West Freeway Church of Christ that day, on Dec. 29, and many credit Wilson for saving many more lives"(https://www.npr.org/2020/09/29/918185532/grand-jury-declines-to-indict-church-security-guard-who-killed-gunman-in-texas). Many more examples of foiled attempted shootings have similar stories, a trained civilian with a firearm stops the criminal shortly after the criminal starts firing. Gun laws won't stop gun violence and mass shootings or access to firearms. Only a trained civilian with a firearm can stop criminals immediately and prevent further violence.

That was heroic, but it was EXCEPTIONAL. Mostly, the "good guy with a gun" is not the answer.

It's been pretty well debunked.

false, the "Good Guy with a gun" is only a myth because places with high crime rate have stricter gun laws, preventing the victim from defending themselves. the website you provided claims shooters target specific groups. "The gun lobby claims that shooters target “gun free zones” because they fear a “good guy with a gun,” and that arming more people in more places will deter crime. However, most mass shooters target a specific person, group, or institution with whom they have a grievance, making it unlikely that a gun-free policy affects the choice of target" (giffords.org). However this is false, because school shootings are quite common in America and are weapon free zones with children as their target. if mass shooters did target a specific person or group, then children would not be a target as most don't cause grievances. The blog provided also says "We know what will lead to less gun violence, and it’s proven gun safety laws and programs—not more guns in untrained hands" this is half true, guns in untrained hands are a problem just as any other tool in untrained hands is a problem. However, guns in trained hands for example Jack Wilson, save many lives.
