Let me take the last first.
Also please note, the number of "bad guys with guns" stopped by a random "good guy with a gun" citizen in all of the past decade and a half of mass shootings is 0.
Not a one.
They were all stopped by either police, or themselves via suicide.
The problem with claiming that zero mass shootings have been stopped by armed civilians is just that: they were stopped. Thereâ(TM)s no weeks-long media feeding frenzy when a mass shooting doesnâ(TM)t happen. But I can definitely present some examples in just the past couple of years where a good guy with a gun stopped a bad guy with a gun.
Clackamas Town Center: An armed individual, obviously attempting to commit a mass shooting, was confronted by a person with a concealed carry license. After seeing a gun being drawn on him, the shooter immediately deviated from his course and killed himself in an adjacent hallway.
Arapahoe High School: A student armed with a shotgun and multiple incendiary devices, shot one person in the face and was attempting to kill more people when an armed school resource officer confronted him. The attacker then killed himself.
Those are just the two most high profile cases in recent history â" a news story that doesnâ(TM)t happen is hard to find, so we never seem to hear about those. Even when they happen, the actual chain of events are still often hard to prove.
It boils down to this: the only thing that stops a bad guy with a gun is a good guy with a gun. Police officer, concealed carry holder, school resource officerâ¦it doesnâ(TM)t matter. Any armed opposition is effective.
Also, the notion that "bad people will always have guns because they ignore laws" is not logically valid, and links two seperate concepts while ignoring the inherent assumptions required to link them. Bad people may ignore laws, but that has little to do with their ability to obtain firearms. Their ability to obtain fireams depends on the efficacy of efforts to disrupt their illicit supply chains.
Read the news out of France lately? The attackers had fully automatic weapons and a rocket launcher. Personal firearm selling, buying, ownership, and possession are all extremely heavily restricted and regulated in France. Have you seen the Colt Model 1911 semiautomatic pistols that are being produced by 3D printing these days? Heck, I can fabricate a STEN submachine gun with the common metal shop tools I have access to in a day or two. I have the complete plans and templates. As far as that goes, it's probably easier to just steal a shotgun and/or pistol from a parked police cruiser (might even get an AR or M4 from the trunk).
Heck, gangs in Brazil make their own guns, and so did Jews in the Warsaw Ghetto and elsewhere in WW2.
If more guns makes people safer and reduces crime, why is America not the safest country on the planet with the lowest crime rate?
Why is it that instead we see the exact opposite, that Amercia has the highest crime rate of all western nations, where the majority of those other nations have far stricter gun control than the US?
Sorry but no. The theory that more guns = less crime is a pile of manure disproven by simple observation.
Lies, damned lies, and statistics. Other nations don't count & categorize data points the same way the US does. Violent crime in the US is at an all time low and has been trending steadily downward for 40 years.
So basically, your entire post is factually wrong and smells like emotionally/ideologically-driven propaganda.
