Hi, Mokthrakaand welcome to OCDO.
Sorry it's taken a few days for anyone to respond. You posted a lot of questions, and it may be difficult to accurately respond to them all.
The questions you're asking are legal questions. There may be specific local and state laws that address what you're asking about. Because "I Am Not A Lawyer" (or IANAL as it's abbreviated), you should not trust mine, or anyone else's advice without looking up all applicable local and state laws for yourself and understanding them completely. The best thing to do is to consult with an attorney. The worst thing to do is get busted and say "Someone on the internet told me it was legal!"
Rather than just answer all of your questions, I'm going to point you to the Oregon Revised Statutes (ORS). They are the complete set of State laws in Oregon. In printed form, they're about 20 books taking up 2 1/2feet long on the bookshelf (the last time I looked at them). You can find them online, themain page is here:
You can search the index for different subjects, however, the section covering most of your questions can be found in ORS chapter 166:
Some of the notable statutes:
166.170 State preemption (Means the State Legislature is the only one that can make firearms laws or grand authority of anyone else to make firearms laws)
166.173 Authority of city or county to regulate possession of loaded firearms in public places (7 cities ban loaded firearms in some or all public places, Portland, Salem, Springfield, Bend, and a couple others. Having a Concealed Handgun License at 21 exempts from these restrictions).
166.240 Carrying of concealed weapons (covers all concealed weapons EXCEPT Firearms)
166.250 Unlawful possession of firearms (THIS one covers concealed handguns, and minors in posession of handguns, as well as clarifies some things it does not cover, like long guns given to a minor with permission from the parent or guardian, and holstered handguns not being concealed (here's where Open Carry is specifically NOT regulated)
166.370 Possession of firearm or dangerous weapon in public building or court facility; exceptions; discharging firearm at school (This one specifically says where nobody can carry a firearm, like schools, city hall, hospitals, etc., except most all of it is exempted for a person with a Concealed Handgun License, except the court facilities part)
There's some other good stuff in that chapter, read through it thoroughly. If you have any specific questions, please ask them, but try to keep it down to 1 or 2 questions per post. You'll get quicker answers that way
Some of your questions may already be answered in other posts, too. Here's one about Open Carry of knives (swords?) http://opencarry.mywowbb.com/view_to...ighlight=sword
Good luck, we look forward to hearing from you, and welcome again to OCDO.
