Firstly, there were other truck attacks.  Just last week - in Israel:   a Muslim truck driver drove into a group of people on a bus stop.  Reported elsewhere.  Not here.  Secondly, I don't know what Donald Trump was referring to, but a sweet girl named Elin was all over the European news after she was raped and killed by a migrant in Sweden at the same time as his statement.   Well, she may not have been very sweet, but she was Swiss, blonde, and very much dead.  The Swiss have said they have never seen such brutality.  Sad.  This may have not been ISIS related, but that won't make much difference to Elin in her early 20s.
