Synopsis by memory:
The Viet judge is the same judge that when told that there are millions of AR15's in the nation for the CA assault weapon case, she asked how many are in CA. Why this matters, is because in common use doesn't apply if only 1 state has X amount of AR's. So, she's asking a stupid question. She also stated during this hearing that she doesn't know how a butterfly knife works or other knives with regard to open carrying them.
1 judge asked if a fixed blade knife has a sheath, why can't a butterfly knife and then you can open carry it.
What I think the 9th is missing is that it's not on us to prove why we want to carry a butterfly knife, but it's on the state to show history and tradition, which they haven't. They haven't show a law back in the historical period that it's illegal to conceal a pocket knife.
The 9th seems to be wanting to make the case moot cause the state changed the law. Even if this law is for open carry only.
I only watched half the vid, so I'll update later once I watch the rest.
