How is a police officer who's carrying out a democratically-enacted law a "criminal" who deserves to be shot?
Maybe I'm mistaken, but I thought we're talking here where if the government outlaws private ownership of weapons, and police come to collect them, people will shoot them?
As TheMeInTeam said, such a law would be unconstitutional, thus the enforcement of such a law would be a criminal act. And since the government isn't going to stop itself, it falls to the people to stop them.
People are missing the point. Did an armed populace help the American government realize that criminalizing marijuana was stupid any faster than other liberal democracies?
Nobody missed the point. You are just bringing up two completely different issues that aren't even remotely related to each other.
And now I ask, how many kids were shot while you were reading my post?

Appeal to emotion. Pretty basic logical fallacy. Wouldn't have expected that from someone who just spent the last page or so arguing from a supposed position of "logic" and "statistics".
I also like how you made the assertion that the 2nd Amendment hasn't done anything good for democracy and when I presented some evidence to the contrary, you just tried to minimize it and started droning on about the War on Drugs instead of admitting that, at the very least, you aren't as correct as you thought you were. I mean, I doubt you had even heard about the Battle of Athens before I brought it up in this thread.
Not only did it obviously fail to deter an overreaching government,
Maybe that's because the government didn't overreach? Just because you believe they did, doesn't make it true. Also, I'll say the same thing that I said last time you tried to use this argument: There's only going to be an uprising if the people don't agree with what the government is doing. A lot of people did, and still do, agree with what the government is doing in the War on Drugs, thus they don't perceive any threat to their civil liberties. People aren't going to take up arms against the government if they don't believe they are being oppressed by that government.
Again, this is not an issue with the 2nd Amendment, but rather one with public perception. In instances where the public has believed they were being oppressed enough to rise up, the 2nd Amendment has actually served them quite well. I also want to point out, the the point of the 2nd Amendment is to act as a safeguard for individual liberty, not democracy. The two don't necessarily go hand-in-hand. For example, if the people "democratically" vote to outlaw the worship of Islam, then the individual liberty of every Muslim in the US would be trampled on despite such a law coming into effect "democratically". With the 2nd Amendment though, Muslims in that scenario would be free to arm themselves in order to resist society's attempts to enforce the ban on the worship of their religion, preserving their individual liberty against the "democratic" will of the people.
In fact, I would say the idea of democracy more often than not clashes with the idea of individual liberty. Democracy tends to place more emphasis on the general collective will of a society, while sacrificing the individual freedoms of the outliers and minority opinions that disagree with that collective will. That's why the Founders didn't set the US up to be a democracy. They valued individualism over collectivism. And if you look, the US referring to itself as a democracy is really a relatively recent development. During the early years of our nation, up until around WWII, the US always referred to itself as "The Republic" or "The Union". After WWII though our politicians started developing a more collectivist attitude and started referring to the US as "our democracy".
There are three countries with the right to bear arms.
They are The USA, Mexico, and Guatemala.
Think about it.
Mexico most certainly does not have the right to bear arms. It may say so in their constitution, but the heavily restrictive gun laws of Mexico show just how much the government actually respects that right. There is literally only one gun shop in the entire country that is legally allowed to sell to private citizens in Mexico. I'm not familiar with gun laws in Guatemala, but a quick search shows they don't really respect the right either. So really the US is the only nation that truly respects the right to bear arms.
Also, not really sure what point you are trying to make here. Are you trying to claim the right to bear arms makes people less safe? If so, what are you basing that on? Statistics? Not a very good metric in my opinion. For example, you may look at that 39,000 gun deaths a year for the US and start feeling pretty unsafe. But if you take a step back and calm down for a second, you'd see that the statistics aren't matching up with your experience. How many times have you been shot in your life? How many times has someone shot at you? How many times has someone even threatened you with a gun? The answer for the overwhelming majority of Americans to all of those questions is going to be in the "hardly any/not at all" category. When you think of it from that perspective, you'll see that you, as an individual, are actually pretty safe from gun violence, as are most other people in the US. That's why it's actually pretty dumb and narrow-minded to base your opinions on statistics. Statistics hardly ever tell the full story on any given issue and that's because statistics are just numbers on paper. They don't factor in all the nuance or personal experiences of each individual in a society.
