If anybody is curious, here are the details from the arrest log:
POSS SWITCHBLADE: VEHICLE
CARRY DIRK OR DAGGER CONCEALED ON THE PERSON
COMMERCE/TRANSFER/POSSESS BILLY CLUB
CARRYING A LOADED FIREARM
The last one is pretty clear. But I suspect that many people don't realize that the first three are crimes. "Switchblade" is any folding knife that can be opened and locked into open position by pressing a button or flicking a wrist. (The definition is pretty technical. There are many popular folding knife models, e.g. CRKT | Folding Tactical Knives
, which are indistinguishable from switchblades for all practical purposes, but are perfectly legal to own or to carry.)
"Dirk or dagger" is essentially any knife with exposed locked blade. This part of the code covers, for example, carrying a concealed kitchen knife in your pocket. (Carrying it in a sheath on your belt or on the bike is OK.)
"Billy club" is not defined, but it essentially means anything that looks like a club, especially if it has a weighted core.
