The chief anti-Holocaust-denialism scholar, Deborah Lipstadt:

Horrified by the attacks tonight in Amsterdam, which are terribly reminiscent of a classic pogrom. I am also deeply disturbed by how long the reported attacks lasted and call on the government to conduct a thorough investigation into security force intervention and on how these despicable attacks transpired. In terrible historical irony, this is happening two days before the grim anniversary of Reichspogromnacht in 1938, when Nazi-sanctioned and led pogroms against Jews erupted across the German Reich.
