We still don't know the name, motive, or origin of the Hague knifer. What we do know about the Hague knifer was that the police said they didn't have reason to believe that this homeless male was a terrorist. He could also have been crazy, reacting to drugs, rejected by women, had TDS on the advent of Trump's visit or had any number of other reasons to stab teens. Holland did a good job of suppressing eyewitness descriptions of him except for this- " He jumped very athletically over benches to get away. He looked like a cheetah,” one witness told NOS." So we know that the Hague knifer was somewhat athletic, probably young, and did not fit stereotypes of down on their luck homeless people not generally compared with cheetahs.
