Paranoia my ass!
I live in Lane County. Last summer there was a family in Florence that came home to their ranch and heard someone shooting on their property. The owner confronted a 20 year old guy, told him it was private property, and asked him to go shoot somewhere else. The guy told him to FO, and ran off into the brush. When the owner was going back to his truck, the trespasser fired some rounds in his direction. The owner went to the house and called the sheriff's office. The cops said that, due to budget cuts, they didn't have anyone to send.
The owner, stupidly, went back to chase the guy off. More rounds fired at the owner. The owner made another call to the cops.
NO COPS EVER RESPONDED TO A GUY SHOOTING AT A PROPERTY OWNER ON HIS OWN PROPERTY.
The next day, the owner's wife saw the trespasser walking across the bridge into Florance. She followed him in her car, and then chased him on foot, until she found where he was going. She called the Florance police, and they arrested him, and turned him over to the sheriff. The trespasser was 'matrixed out' of the county jail within a few of hours of being booked....again due to budget cuts.
Have you heard of the Mongols motorcycle group? Supposed to be the most violent of all of them. The leader of the Springfield chapter was convicted of nine misdemeanor counts associated with trying to run a state worker off the road on I-5. He was matrixed out within 2 days, iirc. They put him on parole, which he immediately violated by leaving the state without tell his parole officer. When he returned, he waited a couple of days (probably to let the drugs clear out of his system), and turned himself in for parole violation. He didn't even spend the night in jail. (Parole violation is SUPPOSED to mean that you have to serve your entire sentence.)
Home invasion, where they come into your occupied house at night, doesn't get you a day in jail in Lane County. Those guys are released to do the same crime night after night.
If you don't think there is a need to be able to defend yourself, your loved ones and your possesions, you have head in the sand.
