I think your right. It reminds me of the number of Democrats that thought 20,000 unarmed black people were shot by the police every year, it was something like 20%... The correct number was 14. Just recently, Brandon Tatum had to explain to a college student that it was not true that the police have killed 90,000 people since 2023..

That level of ignorance is what caused the policy changes which lead to the George Floyd effect (mass increase in crime). So, I can easily imagine that the inverse were true too. If the British public actually understood that they are getting around 1.5 million immigrants every year, this would be a very different conversation than what it already is.
