2. Force projection. When someone who is stronger is trying to rape you, how can you stop them.
3. Overthrowing the yoke. If you do not think it can be done, you are NGMI. How many people in drug cartel countries are powerless because of a lack of weapons.
4. The government is providing the guns to everyone else. Fast & Furious gave guns to criminals and the California Representative or Senator who was pushing for gun control while working to smuggle in weapons. The Christchurch massacre was done by an officer of the government.
We have a mental health crisis whenever someone thinks it is a good idea to commit these acts. Every time it is about taking away guns and not looking at root causes, why did the government bury information about concerns with an individual: look at the Miami incident, the Texas Air Force base, and countless other incidents. We look the other way when people are doing things that seem bad, until they pick up a gun, then we blame the gun for the outcome, not the fact that government agencies looked the other way instead of intervention.
