The accused, Nathaniel Veltman, facing charges of first-degree murder and attempted murder with terrorism allegations, brought a pre-trial motion regarding the admissibility of ideological evidence found on his devices and expert testimony from Dr. Barbara Perry on right-wing extremism.
The court ruled that the ideological documents (including 'A White Awakening', Tarrant's manifesto excerpts, Breivik's manifesto cover, and mass shooting video existence) were admissible, subject to careful presentation and limiting instructions to the jury.
However, the expert testimony of Dr. Perry was deemed inadmissible, as it was not necessary to assist the jury and its potential prejudicial effect outweighed its probative value, particularly given the accused's own explanations and the general notoriety of some concepts.
