Quite a few years ago, we had a sad incident here in my (then) little town. A distraught ex-boyfriend literally drug this poor girl out of the grocery store where she was working, waving a gun around like a crazy man. Two good samaritans that tried to help were rewarded with death, followed by the poor girl, and finally the gunman took his own life. All this thanks to a single action .22 revolver. Six rounds of .22, four dead. Pretty effective if you ask me. I've wondered many times if an armed citizen, or Bubba with his ought six in the gun rack, could have acted swiftly enough to save any of these people.
