I was browsing the HandgunLaw.us web page for Oregon and noticed that they say that in Oregon a "No Firearms" sign has the force of law, meaning that one is criminally trespassing by simply entering the facility armed, CHL or not, concealed or not. That's not what I have been told from other sources and even in my CHL class. It's not my understanding of the law, and it makes a huge difference in my ability to legally carry concealed. My understanding is that someone in charge must ask you to leave, and then if you refuse to leave you are trespassing. I sent an email to the HandgunLaw.us administrators saying they were at odds with the general understanding of Oregon concealed carry law. This is the reply I got: We need to get a definitive answer from somewhere. Anybody got a statement from a rock solid source (preferably a legal professional) on this?
