"peaceable gun owners" is a loaded term (no pun intended). If you're talking about people who insist on carrying guns with them to buy their toilet paper at Wal-Mart "just in case" - then we don't exactly agree on the terms. When these generally clueless/untrained fools have hollywood hero delusions of grandeur by pulling their own guns - as opposed to perhaps finding a way out of the store or a safe hiding place and helping others to find it also - when another crazy man with a gun decides to attack others with his - that's hardly "peaceable" nor even logical in my mind. It took police hours longer to figure out the actual perpetrator because of the wild west mentality of the others with guns at Wal-Mart. A high school of 1700 students is a few blocks away and a dangerous shooter with a gun was on the loose during those critical hours.
