WATCH: Trump-appointed judge chides colleagues' ignorance on guns in unique video dissent

Dressed in his judicial robes, VanDyke went on to show the mechanics of his personal firearms for several minutes. 

VanDyke went on to say he could "explain all this in writing" but that it is "much more effective to simply show" what he means through demonstrating it. He also said he had "rendered inoperable all the guns and gun parts" for the video demonstration for safety purposes. 

"That's important, because your argument turns on whether you can characterize accessories," Van Dyke responded. "So, you would say that the revolver versus semi-automatic is not an accessory, but that, but that a magazine is an accessory. So, what would you think about like a red dot sight? You know, electro optics, which are, which many, many firearms are going to, electronic optics nowadays? They're obviously an accessory, because you could have iron sights. Could you ban those?" 

"Your Honor, I'm not intimately familiar with that," the counsel responded. "And I do want to answer this question and make sure that I save time for rebuttal." The state's attorney went on to say that at issue is whether, as an accessory, it is essential to exercising the right to self-defense.

Later in 2016, Proposition 63 was approved by California voters, which incorporated the provisions of Senate Bill 1446 but also added a criminal penalty for the unlawful possession of large-capacity magazines after the July 1, 2017, deadline.
