Yes, there are very special people out there, to deal with. But, the minute you do, what you suggested with a firearm, you are going to be the one headed off to jail and giving good cc'ers a really bad name. Please, be aware that you are going to be charged with one or more counts against you. Menacing being one of them. "In Oregon, the charge is menacing; however, you do not even have to point the firearm. A person can see it and accompanied with words that could be construed as threatening could get someone charged. Also, sound can too: a person chambering a round can be menacing. The statute is not very helpful because it is very broad, so one would have to go to the Court of Appeals or tales from trial courts to get guidance."
Brandishing is an unjustifiable action. It carries with it an attempt to intimidate someone via the firearm when one is not in danger, and is not justified in the use of the weapon. It is the same as negligently discharging your firearm and claiming self defense. One does not "negligently defend one's self" anymore than one "justifiably brandishes" a firearm.

"Oregon also prohibits those convicted of the following misdemeanor offenses from owning guns:
• Menacing
• Reckless Endangerment
• Stalking
• Strangulation
The legislature also agreed that Oregon courts may now restore convicted felons' rights to possess a gun a year after probation supervision has ended. However, no restoration of rights is available for those convicted of violent felonies involving firearms or the misdemeanor offenses previously noted."
In summary you will never be allowed to own a gun again. And probably somehow lose your fishing privileges in the process ,if you get a judge that thinks it's in the best interest of other ( just an assumption ).
