the first paragraph did not claim it was not a prison, it just claimed it was safe not because it was a prison but for other reasons.

The third paragraph claimed it was a prison but it did not say the safety came from it being a prison.

the third paragraph and first paragraph are not in conflict.

The fact that it is a prison with much surveillance has little to do with its low crime? This is not a credible belief.

I wasn't saying it was wrong or not - I just said the two paragraphs were not inherently contradictory.

That’s why I said “undermined” and not “contradicted”.

I know it’s not true in American prisons but generally not much crime occurs in prison. If Singapore is prison like then it seems that this would at least be a contributing factor to its lack of crime.
