Ignorant U.S. folk do believe they live in the "safe place".
That doesn't mean everyone in the U.S. are ignorant.
The subsection of ignorant U.S. folk is the specific group I am commenting on.
There are people who educate themselves, and seek information everywhere. The U.S. isn't a monolith.
And as I said, I chose the U.S. because they claim to be a safe first world country, however their crime rates are very high. I felt that was a good representation of a high crime nation to compare Japan with. It isn't the highest, but comparing Japan to the highest, instead of something closer to average, would be unfair.
