There are many hypothesis. Too bad the data which could allow us to evaluate them (namely the # of crimes broken down by ethnicity) is <i>deliberately hidden</i>. That&#x27;s why I&#x27;m suspicious of the establishment&#x27;s claims, and why I expect many Europeans are as well.<p>I don&#x27;t find a surge in crime relating to changing demographics implausible. In the US we have widely varying (read: 8-10x) crime rates between ethnic groups, so if our ethnic composition changed we could get significantly more crime as a result. Perhaps Sweden has similar effects. Or perhaps not; but if the data proved otherwise, why would the establishment hide it?
