So 42% said that human rights only benefit criminals and terrorists. That's scary, but not that surprising given how many people read the Daily Mail.
But then 81% said human rights are important for creating a fairer society.
Using my superpower of BASIC MATHS, I deduce that 100-81=19, and 42-19=23, which means that at least 23% of people surveyed thought that human rights benefitting criminals and terrorists was creating a fairer society.
Surveys are only as reliable as the people you ask. And when you ask the British public, you know what to expect.
