Campaigners for a more evidence-based drug policy are horrified. "It’s a classic and appalling example of gutter politics,” says Martin Jelsma, Director of the drugs policy programme of the Transnational Institute. “Accusing the Lib Dems of being ‘soft on drugs and thugs’ is a cheap populist slogan that tries to hide the Labour Party's own co-responsibility for destroying the future of thousands of people by giving them a criminal record for no good reason at all."
Statistics can be a limited and limiting way to understand social issues. When we focus on how many people are affected by a problem, or how much the government spends on tackling it, we start to see numbers instead of people. The opposite is also true, though: without statistical evidence, it’s hard to understand the scale of a problem.
