Multiculturalism strikes at Ohio State University. A Somali immigrant student ran over and/or stabbed 9 students at OSU this morning. First he ran over pedestrians then got out and started stabbing them with a butcher knife before a campus cop shot him dead. Thankfully no student victims have died.
Predictably the OSU administration pretended to be perplexed as to the motive, but given that ISIS recently commanded its followers in the West to randomly attack civilians with "cars and knives", the motive isn't too big a mystery.
Because the people being radicalized against us are already legally here, there isn't much we can do unless there is a multi-person conspiracy and the authorities can detect it. If the attack is by one person, there isn't much we can do to protect ourselves except be armed and ready to fight back.
