I have some questions and I'm sorry if they're dumb. This stuff is so far out of my knowledge base it's ridiculous. I've been on a CA 5250 hold (multiple, actually) for harm to self and as a result I'm not allowed to possess firearms. I live in a house with roommates. We're generally very supportive of each other. My roommates are considering getting a gun because our neighborhood is insane and several of us, myself included, are physically disabled. Would something bad happen legally having a gun in the house if I'm not supposed to own one, and if so, what? "No person who has been adjudicated by a court of any state to be a danger to others as a result of a mental disorder or mental illness shall purchase or receive, or attempt to purchase or receive, or have in his or her possession, custody, or control a firearm..." Possessions, custody, or control sounds a lot like having any access to it is a problem.
