I, of course, do discern a difference. The idea that that is an easy and quick justification or analysis is incredibly naïve.
I don't know, but breaking into a home or property, stealing someone else's property or causing harm to another person without justification (self defense) is pretty straight forward. Also, I don't have to shoot someone from preventing a crime. Just the simple implication that lethal force is an option may be enough to stop the crime in question. This is always the preferred outcome. Hold the suspect until law enforcement is able to take control of the scene. At that point, it is up to the LEO or the courts to sort out the situation.
It's one of those things people have debated and debated to death with no real answers. Further, it is always bizarre when people who tell me the government is often unnecessary and does a lot of overreach suddenly think the most important thing is what the government thinks about any particular action.
I have not seen anyone claim that government is unnecessary. There is a difference between some government and excessive government. What we are experiencing now is a push to excessive government.
But your original point was that you appeared to side with the notion that we should do away with law enforcement. While I stated that it would most likely not affect me, that was not to say that I agreed with it. My implication was that it would be less harmful to me than it would be to those in the urban areas that are generally much more at risk.
Personally, my version of the world is a government that is constrained by our Constitution where the only job of our government is to protect our rights. That is how the founders envisioned this nation. It is the duty of the citizens to provide for and take care of themselves and their neighbors. Most of us in rural areas live that way as much as possible. Therefore a reduction is law enforcement would not affect us nearly as bad as it would those in urban areas that are unable to defend or care for themselves.
