Keeping in mind that gun control proponents didn't need the "cure"---they already have that, in their own minds--our disarmament.
What they needed was the 'disease'. Funny how these incidents are often maximized by "error", "blunders", "bad decisions" and "mistakes", even though there have been enough of them to study thoroughly and eliminate that sort of nonsense.
It is obvious that the best response to someone shooting up the 'hood' near a school, is to stop them--by whatever means--from getting to massed potential victims at the school, especially kids, not to mention other people outside the building.
It is obvious that the sooner the shooter is distracted or taken down, the sooner the killing/wounding stops, especially if the shooter is taken down before getting to where they can do the most harm.
It is obvious that stopping the shooter, by lethal means if necessary, is the primary goal, and enables the prompt administering of first aid and transport of still-living victims to a medical facility.
The sooner those still living victims are transported, the sooner they receive even rudimentary medical attention, the more likely they are to survive.
Yet time and time again, from the Columbine High School incident onward, the obvious behaviour of the shooters pre-event has been ignored. The shooters have managed to gain access, not only to firearms despite being known to be 'troubled', have gained access to buildings and venues with little or no resistance, and LEOs and others have failed to interrupt the shooter and gain control of the scene either before entry to the scene or afterward the incident starts within a time frame that would enhance chances of survival for potential and wounded victims.
Major arterial and venous damage can be survivable for as long as 60 minutes under the right conditions,
source or as little as 2 minutes depending on the vessel, the nature of the damage, the health of the victim, but waiting 60 minutes is a virtual guarantee of exsanguination, hypovolemic shock, and death if EMS or others are not allowed to treat the patient, stop the blood loss and get them to a medical facility.
It was the wait time at Columbine and elsewhere that kept the merely seriously wounded from having a chance to survive their wounds, and in the case of Uvalde, nearly guaranteed that the seriously wounded would die.
Am I the only one seeing a pattern of actions which continues to maximize the body count at these sort of incidents? From failures to stop known disturbed people (even making open threats on social media) from acquiring firearms, entering the venue/scene/building, when shooting outside failing to keep them from accessing larger, penned up crowds, to failures in physical building security, failures to interdict shooters, failures to move other potential victims out of the area (done at Uvalde, at least somewhat), failure to confront the shooter or utilize sharpshooter assets to stop them, failure to enter the building in a timely fashion, failure to get EMS to the victims...
Now, on that day, there were millions of AR-15 (Stoner variant) type rifles across America that were not used at all, some went to the range for target practice, some were used to hunt invasive and damaging species in rural areas, some were even used by law enforcement or non-LEOs to stop crimes, (although legally LEOs have access to new production rifles which can fire full auto or 3 round bursts and not just semi-auto) and maybe one or two were used in crimes.
Much the same can be said of virtually any tool, from knives, to hammers, to shovels, but the only tool the Government wants to take is the one
they are afraid of, and the more they can convince the people they, too should fear that same tool, the better their chance of banning it in hands other than Government's. We all have sufficient historical examples of that situation to see it seldom ends well.
