The very concept of a civilized society requires everyone to living by the laws and rules that society agreed to as their guiding principles. When you live in the US the Constitution, perhaps, the most important of these rules.

If we are going to talk about government derailing and doing as they wish then no piece of paper can protect anyone. At that point it becomes about guns and blood. Which sort of drives the point of the second amendment. That scenario is very, very far from reality in the US for more reasons than one.

The US is one of the few (well, I don't think I know of any other) where you can tell a police officer to go to hell and stop harassing you in a public space due to the rights recognized by the Bill of Rights in the US Constitution. YouTube is FULL of videos showing these kinds of situations. Anywhere else on earth you are far more likely to end-up in jail or worse.

That happens because, at the end of the day, this society is based on a legal set of rules that everyone tends to follow, particularly the important ones. That's the difference.

I know someone is going to bring up the topic of cops doing bad things. Guess what? There are bad cops, bad engineers, bad dentists and bad ice skaters. Humans are not a uniform blob of meat with the same brain. When someone behaves badly, more often than not, they face the consequences of their behavior. This includes violating others' rights.

I know that if you are not in the US the above can be incomprehensible. And that's OK, there's nothing I can say to make you see this realty. It's like a bird trying to explain to a fish what it is like to fly. The lack of context is too extreme.
