Apparently this guy shot himself. Good riddence.
There are always a few bad ones. However, IF the other people in the hotel had been ARMED, THEY could perhaps have prevented a few of the deaths. Police cannot (IMHO) protect us from evil people. Often they arrive after the fact (not their fault). Citizens SHOULD carry and help take care of themselves. I've had enough of us being sitting ducks. Obviously people who have serious mental illness or are criminals are not going to think too much about breaking laws. Sheesh.
