A few years ago, Muslim cabbies at the Minneapolis airport began to refuse to carry passengers who were carrying alcohol. It became a big controversy, as some counter-jihad activists began asking whether the cab drivers would soon begin enforcing other Sharia rules upon their non-Muslim customers. Would they, for example, refuse to carry a passenger who had a ham sandwich? Such concerns were dismissed at the time as hysterical exaggerations of what was presented as a completely innocuous attempt by the cab drivers to exercise their religious freedom. But now, with this incident, we see the next step that we predicted all those years ago: the violent enforcement of Sharia provisions on non-Muslims -- in what still is, for the moment, a non-Muslim country.
