Stories like this make me think long and hard about going ahead and getting my CCL. I am always close to a weapon when inside my home but the randomness of these crimes make me worry. If someone broke in at night while I was sleeping then I would be able to quickly grab a gun. Yet if something happened like the Lawyer story then the gun would be in my room and I would be at the mercy of the criminals. It seems like carrying is the only way to ensure safety in a situation like that.
You don't need a CCL in your own home, OK has a Stand Your Ground Law and The Castle Doctrine if I'm not mistaken.
